Obviously x is 0, so, both equations intersect at (0,1).

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.
