Answer 1

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!
