Question

Two lines, A and B, are represented by equations given below:

Line A: y = x − 2
Line B: y = 3x + 4

Which of the following shows the solution to the system of equations and explains why?

(−3, −5), because the point does not lie on any axis
(−3, −5), because the point satisfies both equations
(−4, −8), because the point satisfies one of the equations
(−4, −8), because the point lies between the two axes

Answer 3

Use substituion it already tells you the value of "y" so plug E1 into E2
\[\huge~x-2= 3x + 4\]

Answer 4

to be a solution, the point needs to be on both lines

Answer 5

you can solve it of just substitute the points (-3, -5) into both equations and see if its true

if not try (-4, -8) and see if its true
