Question

What is the rate of change of the function?

On a coordinate plane, a line with positive slope goes through points (0, negative 4) and (2, 2).
–3
Negative one-third
One-third
3

Answer 1

Explanation:

recall that rate of change is the slope of a line, this also is called a derivative , for later in calculus. :P

given

Point 1 = p1= (0 , -4)

Point 2 = p2 = (2 , 2 )

slope = m

m = (2-(-4)) / (2-0)

note that this question is aimed at messing you up by putting in the extra negative. so it's always important to use the brackets, like i've done, to keep that correct

m = (2+4) / 2

m = 6/2

m = 3

slope is 3
