The equation is .
The equation in slope-intercept form y = mx + c.
Make a table; choose some values for x and find the corresponding values for y.
x |
y = 2 x - 5 |
y |
(x, y) |
- 2 |
Y = 2(-2) - 5 = -9 |
-9 |
(-2, -9) |
-1 |
Y = 2(-1) - 5 = -7 |
-7 |
(-1, -7) |
0 |
Y = 2(0) - 5 = -5 |
-5 |
(0, -5) |
1 |
Y = 2(1) - 5 = -3 |
-3 |
(1, -3) |
2 |
Y = 2(2) - 5 = -1 |

Use these ordered pairs to graph the equation.
1. Draw a coordinate plane.
2. Plot the points.
3. Draw a line through these points.
