Answer:
C. m=1/2 and b=-4
Step-by-step explanation:
To get the slope-intercept notation, you have to convert Ax+By = C to y = mx + b. We can do that by simply moving y to the left side and the rest to the right, or simply use the formula of m = -A/B, b = C/B
We'll do both, they're the same really.
x-2y=8
x-8=2y
2y=x - 8
y = 1/2*x - 4
Alternatively
x-2y=8
A = 1
B = -2
C = 8
m = -(1/-2) = 1/2
b = 8/-2 = -4
