To determine if (1, -7) is a solution to the equation y = x - 8, we substitute the x and y values into the equation and check if the equation holds true.
Given:
x = 1
y = -7
Substituting these values into the equation:
-7 = 1 - 8
Simplifying:
-7 = -7
Since the equation is true when the values are substituted, (1, -7) is indeed a solution to the equation y = x - 8.

To determine if (2, 12) is a solution to the equation y = -6x, we substitute the x and y values into the equation and check if the equation holds true.
Given:
x = 2
y = 12
Substituting these values into the equation:
12 = -6(2)
Simplifying:
12 = -12
The equation is not true when the values are substituted. Therefore, (2, 12) is not a solution to the equation y = -6x.
Given:
