Find the rate of change between:
(1, -1)
(2,4)

rate of change=5

Step-by-step explanation:

Hi there!

The rate of change (or the slope) is calculated from two points with the formula (y2-y1)/(x2-x1)

we are given two points: (1,-1), and (2,4)

let's label the points, to avoid confusion:

x1=1

y1=-1

x2=2

y2=4

now substitute into the formula:

*note: remember that we are subtracting the negative numbers. When it's simplified, we add the numbers.

rate of change=(4--1)/(2-1)

simplify:

rate of change=(4+1)/(2-1)

rate of change=5/1

rate of change=5

Hope this helps!

what level of math? also i don't need to be paid if i can you.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
