Question

7. Bobby wants to check if (4,2) is on the line y = 5x - 18. Lisa also wants to check if (3,-3) is on the

same
line. Show your work, and write a statement (sentence) about who's point is on the line. (8 pts)

Answer 1

Both Bobby's and Lisa's points are on the line.

Explanation:

You just have to plug the points into the equation.

Bobby:

(4,2)

2 = 5(4) - 18

2 = 20 - 18

2 = 2

Lisa:

(3,-3)

-3 = 5(3) - 18

-3 = 15 - 18

-3 = -3

So they both are correct.
