How to find the rate of change using coordinate pairs 3,5 and 7,25

The rate of change is 5/1 or 5

Step-by-step explanation:

(3,5) and (7,25)

The rate of change is the same as finding the slope between two points

To find the slope you use this formula

(Y1-y2)/(X1-X2)

Y1=5 Y2+25

x1=3 X2=7

(5-25)/(3-7)

-20/-4

5/1

5

answer: finding the extract measurements and knowing the points

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
