Question

Find the rate of change between the two points (1, 6.2) and (3, 20) where x is in hours and y is in miles. need the answer asap!

Answer 1

rate of change between points A and B =\[\frac{ y_B - y_A }{x_B-x_A }\]

Answer 2

Let point A be (1,4). What is \[x_A\] and\[y_A\]?

Answer 3

well x_A =1 and y_A=4
Substitute in the equation of rate of change values of coordinates, no matter whether you choose first point as A or not

Answer 4

Do you know how to do that?

Answer 5

well it's \[\frac{ 3-1 }{ 20-6.2 }\]

Answer 6

so its\[\frac{ 2 }{ 13,8 }=0,145\]
