To find:
We need to write the equation of the curve on the graph.
Step-by-step solution:
To write the equation of any line, we need two points on the line:
Two points on the line are (0,2) and (4,0):
m = 0 - 2 / 4 - 0
m = -2/4
m = -1/2
y - 2 = -1/2(x - 0)
y - 2 = -x/2
y = -1/2(x) + 2
Solution of first box is -1/2 and second box is 2.
