Question

How do you solve and graph `p-4<-7`?

Answer 1

Refer the the explanation.

Explanation:

Solving algebraically:
`p - 4 < -7` (original equation)
`p < -3` (solve for p)

For this question, is p the values of x or the values of y?
I don't know what you mean by p because you can't graph p. I'm going to graph both `x < -3` and `y < -3`

graph of x < -3:
graph{x < -3 [-10, 10, -5, 5]}

graph of y < -3:
graph{y < -3 [-10, 10, -5, 5]}

As you can see on both graphs, a dotted line is used, because the value of x < -3 or y < -3 means that it can't equal to -3.
Also, the shaded region of the graph is the solution, because we are just finding all values of x that are less than -3 or all y values that are less than -3.
