Coordinate points are set up as (x, y) so...
x = 3
y = -3
Step 1: Plug 3 into x and -3 in to y in the equation: y = 4x - 1
-3 = 4(3) - 1
Step 2: Solve using basic order of operation
-3 = 12 - 1
-3 = 11
If the end result is equal to each other othen it is on the line y = 4x - 1. If not then the point isn't on the line
Hope this helped!
