Slope Intercept Form

LET'S REVIEW

Slope is the STEEPNESS of a line.

It helps us make predictions and understand proportional relationships.

What is slope?

Multiple Choice

What type of slope?

zero slope

undefined

negative

positive

Multiple Choice

What type of slope?

positive

negative

zero

undefined

Multiple Choice

Find the slope of the line below using rise/run.

$\frac{2}{3}$

$\frac{3}{2}$

$\frac{1}{3}$

Multiple Choice

Find the slope of the line below using rise/run.

$\frac{5}{3}$

$\frac{3}{5}$

$\frac{5}{4}$

Multiple Choice

The slope slope of this line is...

$\frac{-3}{4}$

$\frac{-2}{5}$

$\frac{1}{1}$

NEW INFORMATION

The Y intercept is where a line crosses the Y-AXIS.

The Y Intercept

Multiple Choice

What is the Y-Intercept?

Where a line crosses the Y AXIS

Where a line crosses the X AXIS

The slope of a line

Multiple Choice

What is the y-intercept shown on the graph?

(0, -2)

(3, 0)

(0, 3)

None of these.

Multiple Choice

_{What is the y-intercept of the line?}

y = 1/2

y = 1

y = -1/2

y = -1

Multiple Choice

What is the y-intercept?

-2

-4

NEW INFORMATION

Proportional relationships are written in this form.

m = slope

b = y intercercept

By using our knowledge of these concepts, we can write formulas for lines!

Slope Intercept Form

Example Slope Intercept Form

In this example the slope of the line is 3/1 and the y-intercept of the line is 2.

y = 3x +2

TIME TO PRACTICE

Multiple Choice

Identify the slope of the Equation
y=5x+3

Multiple Choice

Identify the y-intercept of the equation
y=2x+5

Multiple Choice

Which letter in the equation below represents the slope?

y=mx+b

Multiple Choice

Write the equation of the line.

y = -1/3x - 2

y = 1/3x - 2

y = 3x - 2

y = -3x - 2

Multiple Choice

What is the equation by looking at this graph?

y= x + 3

y= -x + 2

y= 2x + 2

y= x + 2

Multiple Choice

Which could be the graph of the equation y = 1/3x - 2?
