Answer:
y = -7
Explanation:
Hey :)
y = mx + b
*m is equal to the slope...
y = (0)x + b
Plug in the point you have...
-7 = (0) (5) + b
-7 = 0 + b
-7 = b
y = (0)x - 7
y = -7
Ignore the (0)x because anything multiplied by 0 is 0 so there's no point in having 0x in your equation.
Answer: y = -7
Hope this helps :)
