Answer:

Step-by-step explanation:

The slope of a line is the rate of change

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (2, 12 ) and (x₂, y₂ ) = (0, 4) ← 2 ordered pairs from the table

m = $\frac{4-12}{0-2}$ = $\frac{-8}{-2}$ = 4

y = 7x + 4 ← is in slope- intercept form

with slope m = 7

Difference between rates of change = 7 - 4 = 3

Answer:

To find the square root of any number you must see what the number that you are trying to find the square of then you look at it and think what number times itself equals this number that you are trying to find the square root of the you solve it...

But in this case you have to divide 8 by 2 then find the square root of 4 which is 2

So there is your answer, Hope this helps:)

Step-by-step explanation:

Well, the answer is 2.
