Answer:
y=5x+44
Step-by-step explanation:
Parallel lines have equal gradients therefore the line will have a gradient =5
Substitute the gradient into the equation y= mx+c. You'll get something like this: y=5x+c
Substitute the given point into the equation. You'll get something like this: 9=5(-7)+c
Calculate the value of c. You'll get 44 as the value of c.
Then substitute the value of c into the original equation. You'll get y= 5x+44
112 + 18 + 20 = 150 total vehicles
112/150 = 0.746 = 74.6% rounds to 75% passenger cars
18/150 = 0.12 = 12% light trucks
20/150 = 0.133 = 13.3% rounds to 13% heavy trucks
P(light truck followed by heavy truck) = 18/150 * 20/149 = 12/745 or 1.6%...I am not 100% sure on this 2nd part
