Finding the X Intercept and Y Intercept
To Graph Standard Form Equations
Now that you've completed your lesson on Graphing Using X and Y Intercepts you are ready to practice! So... let's do it!
Directions: Graph each line using the x and y intercept if possible. If you need to, rewrite the equation in slope intercept form and then graph.

1. 3x +4y = 12
2. 2x +y = 6
3. 2x +5y = -10
4. -3x + y = -4
5. At a concert, David spent $200 on lawn seats and pavilion seats. Lawn seats cost $10 and pavilion seats cost $12.50. The equation representing x lawn seats, y pavilion seats and the total spent is 10x + 12.50 y = 200.
