By setting first x and then y equal to zero it is possible to find the y intercept on ... If x = 0, then f(0) = 1 + .5(0) = 1. If y = 0, then f(x) = 0 = 1 + .5x. -.5x = 1. x = -2 ... If y = 0, then f(x) = 0 = 11 - 2x. 2x = 11. x = 5.5. The resulting data points are (0,11) and (5.5,0) ... From the graph it can be seen that these equations are equivalent.

Specifically, we graphed the two equations y = 2x + 5 and y = (-3/2)x + 2, and ... Now, we can set the right hand side of each equation equal to each other because they both equal y. ... x = 5y in the second equation, then x must also equal 5y in the first equation. .... Also, the point (0, 19/14) works, where x = 0 and y = 19/14.
