The lines intersect at their y-intercept

Explanation:

If two lines have different slopes, they cannot be the same line. However, if they share a y-intercept, that means they cross the #y#-axis at the same #y# value. Since the x value is constant on the y-axis (0), they also share an x-value here. If they share an x value and corresponding y value, they intersect at that point, in this case their y-intercept.
