y = m x + b
when x = 0, y = 4
4 = 0 + b
so b = 4
y = m x + 4
when x = 8, y = 8
8 = 8 m + 4
8 m = 4
m = 1/2
so
y = (1/2) x + 4
What is the equation of the line with a Y intercept of four and a point (8,8)?
A. Y=2x+8
B. Y=2x+4
C. Y=1/2x+8
D. Y=1/2x+4
I really don’t know I have searched and searched and I can’t find anything where it says I can use a y intercept and a point to make an equation. I don’t care about an answer I need and explination
