Question

What are the intercepts of `-3x-8y=4`?

Answer 1

`x = -4/3`
`y = -1/2`

Explanation:

When the line crosses the x-axis the y-coordinate at this point will be zero. By letting y = 0 we get the x-coordinate.

y= 0: -3x = 4 `rArr x = -4/3`

Similarly when the line crosses the y-axis the x-coordinate at this point will be zero. By letting x = 0 we get the y-coordinate.

x = 0 : -8y = 4 `rArr y = -1/2`
