What is the rate of change of a line that contains the points (3,-4) and (2,-4)?

0

Step-by-step explanation:

Notice that the y-coordinates of the points are the same.  That means that in going from one point to the other, we don't move in the vertical direction at all.  From (3, -4) to (2, -4) is a horizxontal change of 1 unit.

Slope = m = rise / run

and in this case m = 0/1 = 0.

The rate of change is the slope and is 0.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

answer is because 4×10=40

and 98×4= is 392

40,392
