Obviously x is 0, so, both equations intersect at (0,1).
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
your equations are:
y = 2x + 1
y = (4/7)x + 1
subtract the second equation from the first to get:
0 = 2x - (4/7) * x
multiply both sides of this equation by 7 to get:
0 = 14x - 4x
combine like terms to get 0 = 10x
solve for x to get x = 0
when x = 0:
y = 2x + 1 becomes y = 1
y = (4/7)x + 1 becomes y = 1
the common solution to both equations is when x = 0.
when x = 0 in both equations, y = 0 in both equations.
