Find the X- and y intercept -2x-4y=-20

We should change this equation to the slope-intercept form first. y = mx + b

So all we have to do is move the term with the x variable in it to the other side by adding it (inverse of a negative).

-2x - 4y = -20

+2x on both sides

-4y = 2x - 20

Now, we divide the whole thing by -4 to get y alone.

y = -1/2x + 5

To calculate for y, we must set x to 0.

y = 0x + 5

y = 5

To calculate for x, we must set y to 0.

(0) = -1/2x + 5

Move 5 by subtracting 5 to both sides.

-5 = -1/2x

Now we have to get x alone, to do that, we must divide by -1/2 on both sides.

10 = x

Answers:

y = 5
x = 10
