Question

(1.) Select all the points that are on the graph of the line 2x + 3y = 7

a. (-1, 3)
b. (2, 1)
c. (3, 1)
d. (2, -1)
e.(8, -3)

Answer 1

a, b, e

Explanation:

The first number is x, the second is y.

substitute those numbers into x and y and solve the equation. If you get 7, the point lies on the line and vice versa.

To do a:

2 x -1 + 3 x 3 = 7

-2 + 9 = 7

True. It lies on the line.
