Question 2 What is the slope and Y intercept for the following equation? 2x - 4y = 8 A. m=2 yint = 1/2 B. m= -1/2 yint = 2 C. m= -2 yint = -1/2 D. m= 1/2 yint = -2 D CA

Answer 1

the equation is of the form y = mx + b, where m = slope and y-intercept = b, in this case

$\begin{gathered} 2x-4y=8 \\ x-2y=4 \\ x-2y-x=4-x \\ -2y=4-x \\ -\frac{2y}{-2}=\frac{4}{-2}-\frac{x}{-2} \\ y=-2+\frac{1}{2}x \\ y=\frac{1}{2}x-2 \end{gathered}$

answer:

m = 1/2

y intercept = -2
