Question

Is the point (-18, 31) on the line y = -0.5x + 22?​

Answer 1

Yes

Explanation:

Remember: (x, y)

Substitute the coordinates to the variables (x and y):

Equation: y = -0.5x + 22

Substitution: 31 = -0.5(-18) + 22

31 = 9 + 22?

Correct! The coordinates substituted to its variables solve and make the equation make sense!
