Answer:
the answer is d
Step-by-step explanation:
Y=mx+b where m=slope=(dy/dx) and b=y-intercept (value of y when x=0)
You have two points...(1,-2),(3,2) so
m=(y2-y1)/(x2-x1)=(2--2)/(3-1)
m=4/2=2 now that you have the slope...
y=2x+b, you can use either point to solve for the y-intercept, I'll use (3,2)
2=2(3)+b
2=6+b
b=-4 so the line is:
y=2x-4
X = (w + y + z) / 4....multiply both sides by 4, cancelling the 4 on the right
4x = w + y + z ....subtract w and subtract z
4x - w - z = y....answer is A
