• a=1

• a=17

• a=-17

• a=-1

Solve 4x - z = y for x.

• x= $\frac{y+z}{4}$

• x= $\frac{y-z}{4}$

• x= y+z-4

• x= $\frac{y}{4}+z$

Select the equation with a y-intercept of $\frac{3}{2}$   and a slope of 2 in slope-intercept form.

•  $y=\frac{3}{2}x+2$  

•  $x=2y+\frac{2}{3}$  

•  $y=2x+\frac{3}{2}$  

•  $2x+y=\frac{3}{2}$
