Replace x and y’all with the point and solve the equations
1. 2(0.5)+ 4(-6.75) = 1 + -27 = -26
This is true so is an answer.
2. Y = 0.5-7.5 = -7, -7 is not -6.75 so this is not true.
3. 2(-6.75) = 0.5 + 13
13.5 = 13.5
This is true so is also an answer.
4. -6.75 = 0.5(0.5) -7
-6.75 = 0.25-7
This is true so also an answer.
