Answer:
slope m = (5+1)/(-6+8) = 6/2 =3
A line does not describe a slope.
Answer:
5x+8=26.50
Step-by-step explanation:
Because the books are equal in price, we can use x to represent the price of the books and 5 to represent the amount, so it would be written as 5x. Then we add 8 because that's the price of the one DVD. It tells the total is 26.50, so the full equation written would be <u>5x+8=26.50</u>
The second equation has 4x in it t. So to eliminate X, you need to multiply y = x-2 by -4, so the x would become -4x.
