Answer:
y= -2x + 8 or y= -2/1x + 8
Explanation:
So first you would do the slope formula
m= y2-y1/x2-x1
m= 0 - 8 / 4 - 0
It does not matter which is x1 and x2, or y2 and y1.
Subtract and you will get: -8/4...
then simplify: -8/4 divided by 4 = -2/1 <<That's your slope
plug it into the equation: y=mx+b
y=-2/1x + b
plug in one of the points into the formula (does not matter which)
8=-2/1(0)+b
solve for b
b=8
so the formula is
y= -2/1 x + 8
or
y= -2x + 8
