Answer:
Step-by-step explanation:
Slope intercept form is
y=mx+b
(m) is slope
(b) is y intercept
The y intercept is where ethe line crosses the y axis [vertical axis]
The line crosses at (0, 7)so our b=7, now we need slope.
The formula for slope is (y₂-y₁)/(x₂-x₁),
which is the y of the second given point minus the y of the first given point divided by the x of the second given point over the x of the 1st given point.
(-2-7)/(8-0)
-9/8 is our slope
put our (m) and (b) into the formula
y=-9/8x+7
