An airplane on autopilot took 5 hours to travel 4,200 kilometers. what is the unit rate for kilometers per hour?

approximately 700 km per hour

Step-by-step explanation:

5 * 60 = 300 4200/ 300 = 14

14 * 60 =840

840 * 5 = 4200

the answer is c)8

step-by-step explanaction:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
