Question

Which equation represents the line passing through the points (1, 1) and (-2, 13)?

4x + y = 5
x + 4y = 5
x - 4y = 5
4x - y = 5

Answer 1

It seems to me to be the first one

Answer 2

if you were to plug in your two points in the equations, would they work?
pt 1 pt 2
eq 1 Y Y
eq 2 Y N
eq 3 N N
eq 4 N N
so yes, it is the first one.
