Question

the equation for a line and a point is given. determine whether the point is on the line or not.

y= -2x + 8 ; A (-4,0)

how do you solve this please? like a hint or smtn if u dont wanna give me the answer.

Answer 1

put the point into the equation

If LHS = RHS then the point is on the line

0 = -2(-4) + 8

0 = 8 + 8

0 = 16

LHS ≠ RHS therefore the point is not on the line

Answer 2

Just substitute -4 for x( -2*-4=+8+8=16) so when x= -4 y=16 so no
