  Step 1: She should have added 25

Step-by-step explanation:

The second step shows that Erica wanted the result that -25 would disappear from the left side of the equation. However, by subtracting 25, she would end up with -5x - 50 on the left.

To make the sum of -25 and some number be zero, the added number must be the opposite of -25. That is, 25 must be added (to both sides).

In the attachment, the sum in the red rectangle is -50, not 0.

what? ?

what type of question is thiss

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
