Question

How do you find the x and y intercept of `5x + y = −8`?

Answer 1

x-intercept = `-8/5`
y-intercept = `-8`

Explanation:

Basically when either the x or the y is intercepted, one of them have to equal to zero. For example, when the line crosses the y-axis, x has to equal to zero. Knowing this, we can just simply substitute 0 as x or y and obtain the values

`5x + (0) = -8` `therefore` `5x=-8, x=-8/5`

`(0)+y=-8` `therefore` `y=-8`
