Two cars leave towns
400

kilometers apart at the same time and travel toward each other. one car's rate is
12

kilometers per hour less than the other's. if they meet in
2

hours, what is the rate of the slower car?

56

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

a - base

b - exponent

so,
