You just started a lawn mowing company! It cost you $11 to buy enough gas to mow lawns for a week. You are going to mow 7 lawns this week. You charge $8 for mowing a lawn. What is the y-intercept?

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
