For this case we must find the solution of the following expression:
If we isolate a term and we equate to zero, we have:
Subtracting 7 on both sides of the equation we have:
Thus, the solution of the expression is given by:

Hi there! The answer is -2.
We can find the slope of a formula by using the following formula:
x2 and y2 don't mean squared, but the x and y coordinate of our second point.
First we need to find two points on the line. Ijn this particular case we have (-3, 3) and (1, -5). Now we can fill in the formula.
Therefore, the third answer is correct.
~ Hope this helps you!

Answer:
Eric's father work 5 hours each afternoon
Step-by-step explanation:
Let x be the no. of hours Eric's father work each afternoon
He works for hours in morning each day = 3
He works for total hours in morning in 5 days=
He works for total hours in afternoon in 5 days=5x
We are given that he works a total of 40 hours each 5-day workweek.
ATQ
15+5x=40
5x=25
x=5
Hence Eric's father work 5 hours each afternoon
