Graphing
Equations: 4x - y = 20
-3x - 2y = -12
| 1. 4x - y =20 2. -3x - 2y =-12 |
The first step in solving this is to solve each equation for y or find the x and y intercepts. |
| 1. y int. = (0,-20, x int. = (5,0) 2. y int. = (0,6), x int. = (4,0) or 1. y = 4x - 20 2. y = -3/2x +6 |
After that you would then graph both of the equations on your calculator by going to the "y =" button and typing in your equations. Then press graph. Then go to "2nd" "trace" "5" then enter three times. This will give you the intersection for your line. |
