Graph the equation-5x-2y=-10 by plotting the points
bearhunter [10]

Answer:

y = -2.5x + 5

Explanation:

Convert -5x - 2y = -10 into slope-intercept form: y = -2.5x + 5

You can start solving for and graphing points by putting numbers in for 'x' in the equation, and the answer you get out will be y.

Ex: -2.5(7) + 5 = -12.5

7 is the number we inserted for x, so it is the x value. -12.5 is the number we got out of the equation, so it is the y value.

The points will now look like this: (x, y) but for the example they would look like (7, -12.5)

Plot the numbers, x being on the horizontal axis, y being on the vertical axis.
