Graphing & Writing Equations of Lines

Review

How to graph lines:

y=mx+b

Graph the y-intercept.

Count rise over run to graph the slope. Remember:

Some text here about the topic of discussion

How to write equations of lines:

y = mx+b

Write the y-intercept. (this goes where b is)

Count rise over run to find the slope. (this goes where m is)

Multiple Choice

Where do I begin?

Y = -2/5x -4

At -4 on the X-axis

At 4 on the y-axis

At (-2,5)

At -4 on the y-axis

Multiple Choice

Given that the slope is 2/3 and the y intercept is -3 what is the equation of the line?

y = 2/3x - 3

y = 2/3x + 3

y = -2/3x - 3

y = -2/3x + 3

Multiple Choice

Which graph represents the equation:

y = 2x + 2

Multiple Choice

Find the equation of the line in slope-intercept form.

y = - 1/4x - 3

y = 1/3x + 3

y = - 1/4x + 2

y = 1/3x -3

Multiple Choice

Identify the slope and y intercept in the equation of the line: y = -1/3x + 1

Slope: 1/3
y-intercept: 1

Slope: 1/3
y-intercept: -1

Slope: -1/3
y-intercept: 1

Slope: -1/3
y-intercept: 0

Multiple Choice

If m=3 and b=6, what is the correct slope intercept equation?

y=3-6

y=3x-6

y=3x+6

y=6x+3

Multiple Choice

What is the slope of the line with the equation $y\ =\ -\frac{3}{2}x\ +\ 4$

$-\frac{3}{2}$

$\frac{3}{2}$

$4$

$-4$

Multiple Choice

What is the y-intercept of the line with the equation $y\ =\ -2x\ +\ 4$

$-2$

$2$

$4$

$-4$

Multiple Choice

Graph the line with the equation $y\ =\ -\frac{2}{3}x\ +\ 4$

Multiple Choice

Graph the line with the equation $y\ =\ -\frac{1}{3}x\ -\ 4$

Multiple Choice

Which y - intercept and slope applies to the graph?

y - intercept = 2, slope = 2

y - intercept = -2, slope = 1/2

y - intercept = -2, slope = 2

y - intercept = 1, slope = 2
