Write in slope intercept form
5x - 3y = -9

• y = (5/3)x - 3
• y = (5/3)x + 9
• y = (5/3)x + 3
• y = (3/5)x + 3

Write the equation in slope-intercept form:
-3y + 5x = 12

• y = -4 + 5x
• y = -4 + 5/3x
• y = 4 - 5/3x
• y = 12 + 5x

Which of these represents slope-intercept form?

• y - y₁ = m(x-x₁)
• Ax + By = C
• y = mx + b

What is the slope intercept form of the equation
4x - 8y = 72

• y = -4x + 72
• y = -4x - 9
• y = 1/2x - 9
• y = 4x + 9

what is the slope intercept form for the equation -2x + 8y = 2

• y = -2x + 8

• y = 1/4x + 1/4

• y = -1/4x - 1/4x

• y = 2/8x + 4

what is the first step to solve for slope intercept form on

-x + 4y = 11

• subtract 11 from both sides

• add x to both sides

• subtract x from both sides

• put in th y=

• y=-3x+1

• y=3x+1

• y=1/3x+1

• y=-1/3x-1

The equation is now solved for y.

y = ¹/₂x - 5

Which is the graph of this equation?

• 
• 
• 
• 

Identify the form of the following linear equation:

x = 4y - 8

• Standard Form

• Slope - Intercept Form

• Neither

What needs to be moved second when converting from Slope Intercept to Standard Form, for y=½x +10?
y=mx+b  ---> Ax+By=C
The first step was to subtract ½x so now it looks like
-½x +y = 10
Then you multiplied by -2
Now what will it look like?

• -2x -2y=10
• -2x+2y=20
• x-2y=20
• -x+2y=10
