Question

This graph shows the line `3x+2y=18`. Select all of the points that are on this line.

Answer 1

(6,0), (0,9), (2,6)

Explanation:

If a point is on a line, then the equation should be true when you plug in the x and y values.

(0,6): 3*0+2*6 = 18 -> 12 = 18, false

(6,0): 3*6+2*0 = 18 -> 18 = 18, true

(0,9): 3*0+2*9 = 18 -> 18 = 18, true

(9,0): 3*9+2*0 = 18 -> 27 = 18, false

(2,6): 3*2+2*6 = 18 -> 18 = 18, true
