Question

y-3x=0
need to solve to gets points and graph

Answer 1

Just plug in any arbitrary number for one of the variables, and see what the other variable's value is.

y - 3x = 0
x = 0
y - 0 = 0
y = 0
(0,0)

y= 6
6 - 3x = 0
x = 2
(2,6)

Answer 2

y - 3x = 0
y = 3x

plug in numbers to make a graph

y = 3(1)
= 3

y = 3(2)
= 6

now go back and find y

3 = 3x
= 1

6 = 3x
= 2


so two points on the graph are (1,3) and (2,6)
