Answer:

(x,y) = (0,7)

(x,y) = (3,7)

Explanation:

The question and the attached image are different. However, the attached image answers the question y = -4 correctly.

So, I will solve for:
y = -x + 7

Given

y = -x + 7

Required

Possible values of x and y

Let x = 0:

y = -x + 7

y = -0 + 7

y = 7

So, we have:

(x,y) = (0,7)

Let y = 4

y = -x + 7

4 = -x + 7

Collect Like Terms

x = -4 + 7

x =3

So, we have:

(x,y) = (3,7)

So, all you need to do is: assume a value for either x or y, then solve for the other variable.
