The y-intercept of a line is at point x=0. Substitute

5x + 7y = 14

7y = 14

y = 2

So the y-intercept of the given line is at point (0,2).

5x+7y=14 Converting it into y = mx +c format We get, y=-5/7x +2 Hence intercept is +2 units Hence its coordinates are (0,2)

It actually is y=mx+b . Also you can just set x to zero so u have 7y=14 and solve to get y=2, thus the point is (0,2)
