Point-Slope Form

Point-Slope Equations need 2 things....

A point
A slope

Multiple Choice

Which of these is point-slope?

$y-y_1=m\left(x-x_1\right)$

$y=mx+b$

$Ax+By=C$

Multiple Choice

Write an equation of the line going through the point (-4, 1) with a slope of 1/3.

$y-1=\frac{1}{3}\left(x+4\right)$

$y+4=\frac{1}{3}\left(x-1\right)$

$y-4=\frac{1}{3}\left(x+1\right)$

$y+1=\frac{1}{3}\left(x-4\right)$

Multiple Choice

Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

y + 7 = -1/4(x - 4)

y - 4 = -1/4(x + 7)

y + 7 = 4(x - 4)

y - 7 = -1/4(x - 4)

Fill in the Blanks

Name the slope of this line:

$y+1=-\frac{5}{4}\left(x-3\right)$

Type answer...

Multiple Choice

Name the point given in this line: $y+1=-\frac{5}{4}\left(x-3\right)$

(3, 1)

(-3, -1)

(-3, 1)

(3, -1)

Fill in the Blanks

Find the x-value of the point in Student B's equation

Student A: y - 3 = 4 (x + 2)

Student B: y + 1 = 6 (x - 5)

Student C: y + 4 = -3 (x + 8)

What if I'm given just 2 points?

Fill in the Blanks

What is the slope of a line passing through the points (-2, -3) and (4, 3)?

USE DESMOS

Multiple Choice

Write the equation in point-slope form for the line that contains the points

(-2, -3), (4, 3)

y - 3 = 1(x - 2)

y + 3 = 1(x + 2)

y -3 = -1(x + 2)

y + 3 = -1(x - 2)

We also learned how to transform Point-Slope equations into Slope Intercept form.

Poll

Is this slope intercept form?

$2y\ =4x\ +10$

yes because it's $y=mx+b$

no, because there is a coefficient on the y. You need to divide the entire equation by 2 first in order to get $y=mx+b$

Multiple Choice

What is the equation of the line y + 5 = -3(x - 6) in slope intercept form?

y = -3x - 23

y = -3x -13

y = -3x - 11

y = -3x+13

Fill in the Blanks

Transform this point-slope equation into slope intercept form:

$y-2=3\left(x+4\right)$

Type answer...

Multiple Choice

Two lines that are perpendicular lines have ...

Slope that is opposite reciprocals

No Slope

Slope that is the same

none of the above

Multiple Choice

Two lines that are parallel will have ...

Slope that is opposite reciprocals

No slope

Slope that is the same

none of the above

Multiple Choice

y = -2/3x + 2
y = 3/2x + 9
These lines are...

Parallel

Perpendicular

Neither

Multiple Choice

y = 3x +2
y = 3x - 3
These lines are...

Parallel

Perpendicular

Neither

The same line

Multiple Choice

What is the equation of this line in slope-intercept form?

y = 2x + 5

y = -2x + 5

y = -2x

y = 5

Multiple Choice

Which equation is perpendicular to:
y = -6x +2

y = 6x +1

y = 1/6x +4

y = -6x +3

y = -1/6x +5

Multiple Choice

Write the equation in slope-intercept form: 2x + 2y = 6

y = - x + 3

y = x + 3

y = 2x +6

y = - 2x + 6

Solving Multi-Step Equations

Follow along and answer the question in this Quizizz Lesson.

In case you need a little help, I have included some informational slides to help out.

Simplifying before Solving

As you can see in the photo to the right, some equations must be simplified before they can be solved.

The goal is to simplify the equation into a two-step equation.

The first 3 steps of this problem show how to simplify the equation.

After simplifying, we can see that we have a two-step equation and we use inverse operations to solve.

If an equation contains parentheses, like the ones you see in these examples, you must distribute the value on the outside to get rid of the parentheses.

Remember, distribute means to multiply!

Distributive Property

With all POSITIVE values.

Be careful with negatives!

Multiple Choice

5(a + 6)

5a + 6

a + 30

5a + 30

5a - 30

Multiple Choice

Which of the following is equivalent to 2(c - 8)?

2c - 16

2c + 16

2c - 8

c - 16

Multiple Choice

When an equation has parentheses, which operation should we use to simplify and get rid of the parentheses?

Add

Subtract

Multiply

Divide

Multiple Choice

-9(g - 3)

-9g + 27

9g + 27

-9g + -27

-9k - 27

Sometimes, to simplify an equation, it could involve combining like terms.

As you can see in the example, regrouping the like terms makes it easier to combine.

Combine Like Terms

When combining like terms, pay attention to the sign in front of each term.

Combining could mean we add or subtract.

Multiple Choice

Simplify the expression:

$3a+7-2a$

12a

a + 7

5a + 7

Multiple Choice

Simplify the expression:

$n-10+9n-3$

9n-3

10n -13

Multiple Choice

Simplify the expression:

$4x-3+2-2x$

6x + 5

2x + 1

2x - 1

6x - 1

Multiple Choice

-13w - 23

-5w - 9

Solving Multi-Step Equations

The first 3 steps of this problem show how to simplify the equation.

After simplifying, we can see that we have a two-step equation and we use inverse operations to solve.

On the next few slides, you will be asked to simplify and solve a few equations. Please complete these examples on your whiteboard.
