Answer:
Well for constructing your gonna need a compass and measure the length of the line your constructing and a drawing is just a free draw without a compass perpendicular lines are straight on both sides
You can take the first point as the origin O(0,0) and the second one (-2,0.5) for easier calculations.
Find the slope, m = (y2 - y1)/(x2 - x1)
= -2-0 / -0.5-0 = 2/0.5 = 4
now take (x,y) = (0,0) and m= 4
use the point slope form
(y - y1) = m(x - x1)
(y - 0) = (4)(x - 0) ......taking (x1,y1) = (0,0)
y = 4x + 0 ...... in the form of y = mx + b
I hope I was helpful:)
Rate of change is -2 because you can do rise over run to find the constant rate of change, and since you are going down you have a negative slope.
