Alg1 lesson 4-5

1. 1. Graph y = 2x – 3 <br />
2. 2. Graph y = -3x + 1 <br />
3. 3. Graph 4x + 2y = 4<br />4(0) + 2y = 4<br />0 + 2y = 4<br />2y = 4<br /> 2 2<br />y = 2<br />
4. 4. Graph 4x + 2y = 4<br />4(1) + 2y = 4<br />4 + 2y = 4<br />-4 -4<br /> 2y = 0<br /> 2 2<br /> y = 0<br />
5. 5. Graph 4x + 2y = 4<br />4(2) + 2y = 4<br />8 + 2y = 4<br />-8 -8<br /> 2y = -4<br /> 2 2<br /> y = -2<br />
6. 6. Graph 4x + 2y = 4<br />4(3) + 2y = 4<br />12 + 2y = 4<br />-12 -12<br /> 2y = -8<br /> 2 2<br /> y = -4<br />
7. 7. Graph 4x + 2y = 4<br />
8. 8. Graph x – y = -1<br />0 – y = -1<br /> – y = -1<br /> -1 -1<br />y = 1<br />
9. 9. Graph x – y = -1<br />1 – y = -1<br />-1 -1<br /> – y = -2<br /> -1 -1<br />y = 2<br />
10. 10. Graph x – y = -1<br />2 – y = -1<br />-2 -2<br /> – y = -3<br /> -1 -1<br />y = 3<br />
11. 11. Graph x – y = -1<br />3 – y = -1<br />-3 -3<br /> – y = -4<br /> -1 -1<br />y = 4<br />
12. 12. Graph x – y = -1<br />
