Question

y=x+4 (-7,1) please help me solve this

Answer 1

just plug in the order pairs

Answer 2

y=x+4(7)
y=x-28
y-28=x

OR

y=x+4
y+4=x

Answer 3

(-7, 1) are x,y coordinates. Just plug in the numbers.

y=x+4
1=x+4
1-4=x
-3= x

and to solve for y

y=(-7) + 4
y= -3

So the answer is (-3, -3)
Hope this helps :)
