Draw a graph to back up your answer

d<9 (graph explained below)

Step-by-step explanation:

First we need to solve the inequality, which means we want to get the variable by itself.

5d-13<32     Add 13

5d<45         Divide by 5

d<9        

Now we need to graph the solution.

Since we are using the less than symbol the circle will be open and the line will be going to the left. Imagine the inequality symbol as an arrow telling you which way to go. So when you graph you will start at 9 with an open circle with the arrow going to the left.

You can now check your solution. So we can fill in d for any number, I'll use 0.

5(0)-13<32     Simplify

-13<32

If you want to check it again with other numbers just to make sure I would strongly suggest it.

b

step-by-step explanation:

ez

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
