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 -1 (2, -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.
