Multiple Choice
What is the algebraic equation for the following table?
y = x + 3
y = 3x
y = x ÷ 3
y = x - 3
17
The questions to follow will practice this conversion and using it.
Convert to y=mx+b
Sometime the ACT will give you linear equations in standard form(ax+by=c) and ask you do stuff with it. Knowing how to convert it to y=mx+b will help you answer those questions.
You do that by solving for y.
18
Multiple Choice
Write the slope intercept form of the equation 3x - 2y = -16
y = -3x - 8
y = -3x + 8
y = -3/2x - 8
y = 3/2 x + 8
19
Multiple Choice
Write the slope intercept form of the equation 13x - 11y = -12
y = 13/11x + 12/11
y = 13x - 11
y = -13/11x -12/11
y = x + 1
20
Multiple Choice
Write the slope intercept form of the equation 9x - 7y = -7
y = -9/7x + 1
y = 9/7x + 1
y = -9/7x - 7/9
y = 9/7x + 7/9
