Question

What is the slope of the line 2x - 5y = -10?

Answer 1

-5y=-10-2x, y=2+2/5x so the slope is 2/5

Answer 2

Start with the given equation

Let's find the x-intercept

To find the x-intercept, let y=0 and solve for x:
Plug in

Simplify

Divide both sides by 2


Reduce



So the x-intercept is (note: the x-intercept will always have a y-coordinate equal to zero)

Start with the given equation

Now let's find the y-intercept

To find the y-intercept, let x=0 and solve for y:
Plug in

Simplify

Divide both sides by -5
