Question

Calculate the rate of change for the points (-2, 1) and (-5, 7).

Answer 1

so there two points one with coordinates (-2,1) and the second with (-5,7)

what you think how you get from x=-2 the x = -5 and from y=1 the y=7 ?

Answer 2

what mean this rate of change ?

Answer 3

-2-3= -5
1+6=7

Answer 4

you put the 2 points in the slope formula and then you have the rate of change

Answer 5

so how would i do that

the formula is \[m=\frac{ y _{2}-y _{1}}{ x _{2}-x1 }\]
so you =ld imput the point into the equation.
\[m=\frac{ 7-1 }{ -5--2 }\]
then you would simplify giving you \[m= \frac{ 6 }{ -3 }\]
then you simplify the fraction giving you -2

rate of change is the slope btw

Answer 8

so -2 would be the answer?

Answer 9

yea im pretty sure
