Heather went for a drive in her new car. She drove for 201.6 miles at a speed of 63 miles per hour. For how many hours did she drive?

3.2

Step-by-step explanation:

201.6/63 is 3.3

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

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.
