Answer:
[tex](x,y) = (0,7)[/tex]
[tex](x,y) = (3,7)[/tex]
Step-by-step explanation:
The question and the attached image are different. However, the attached image answers the question y = -4 correctly.
So, I will solve for: [tex]y = -x + 7[/tex]
Given
[tex]y = -x + 7[/tex]
Required
Possible values of x and y
Let x = 0:
[tex]y = -x + 7[/tex]
[tex]y = -0 + 7[/tex]
[tex]y = 7[/tex]
So, we have:
[tex](x,y) = (0,7)[/tex]
Let y = 4
[tex]y = -x + 7[/tex]
[tex]4 = -x + 7[/tex]
Collect Like Terms
[tex]x = -4 + 7[/tex]
[tex]x =3[/tex]
So, we have:
[tex](x,y) = (3,7)[/tex]
So, all you need to do is: assume a value for either x or y, then solve for the other variable.
