Writing Linear Equations Quiz

Question 1

Write the equation in slope-intercept form for a line with slope $m=3$ and $y$-intercept $b=-2$.

Accepted Answer

$y=3x-2$

Answer

$3y=x-2$

Answer

$y=-2x+3$

Answer

$y=3x+2$

Question 2

Convert $3x-2y=8$ to slope-intercept form.

Accepted Answer

$y=\frac{3}{2}x-4$

Answer

$y=\frac{2}{3}x-\frac{8}{3}$

Answer

$y=\frac{3}{2}x+4$

Answer

$y=-\frac{3}{2}x+4$

Question 3
