Answer:
Step-by-step explanation:
Remark
You can use the two points marked to find the slope. One of them is the y intercept which you need to get the equation.
(0,4) is one of the points. This is the y intercept.
(8,0) is the other point you can use
Slope
m = (y2 - y1)/(x2 - x1)
Givens
y2 = 4
y1 = 0
x2 = 0
x1 = 8
Solution
m = (4 - 0) / (0 - 8)
m = 4/-8
m = - 1/2
y_intercept = 4
Equation
y = -1/2 x + 4
