Question

Find the x and y intercepts of the linear equation 2x - 4y = -20

Answer 1

see explanation↓

Explanation:

We are given the following equation of a line:

`2x-4y=-20`

To determine the x-intercept we must set "y = 0":

`2x-4(0)=-20`

`2x=-20`

Now, we divide both sides by 2:

`x=-(20)/(2)=-10`

Therefore, the "x" intercept is -10.

To determine the y-intercept we set "x = 0":

`2(0)-4y=-20`

`-4y=-20`

Now, we divide both sides by -4:

`y=(-20)/(-4)=5`

Therefore the y-intercept is 5.
