Specifically, we graphed the two equations y = 2x + 5 and y = (-3/2)x + 2, and noted ... in each equation (for the intersection point), we can set the y-values equal to each other! .... and 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.

Learn to solve the system of equations y = -5x + 8 and 10x + 2y = -2 using substitution. ... Systems of equations with substitution: -3x-4y=-2 & y=2x-5 .... =>z =-5. Plug that value in to solve for X and you get: =>x=12(-5) Simplify: .... After you do so, you will find the B. Then substitute B in the first equation to find a ..... -x + y + z = 0

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.
