Answer:

The slope is 2/5

Explanation:

Slope-Intercept form: y = mx + b

  • m = slope
  • b = y-int

To find the slope, you must rewrite the equation in slope-intercept form by using inverse operations to isolate the y.

1) Subtract 2x from both sides of the equation:

  • 2x - 2x - 5y = 9 - 2x
  • Result: -5y = -2x + 9; Notice the numbers are rearranged to keep the slope-intercept form. As long as you keep the correct sign, you can rearrange them.

2) Divide both sides by -5:

  • - 5y/- 5 = - 2x/- 5 + 9/- 5
  • Result: y = 2/5x - 9/5

b = -9/5

m (slope) = 2/5
