Question

How do you find the x and y intercept of `2x + -8y = -10`?

Answer 1

`x`-intercept is `-5` and `y`-intercept is `5/4`

Explanation:

If one has to find `x`-intercept, one should put `y=0` and solve for `x`.

Hence as `2x+(-8y)=-10` and putting `y=0`

we get `2x=-10` or `x=-5`

and to find `y`-intercept, one should put `x=0` and solve for `y`.

Hence as `2x+(-8y)=-10` and putting `x=0`

we get `-8y=-10` or `y=(-10)/(-8)=5/4`

Hence `x`-intercept is `-5` and `y`-intercept is `5/4`
