Question

What are the intercepts of `-x-4y=9`?

Answer 1

`color(brown)("x-intercept " = a = -9, " y-intercept " = b = -9/4`

Explanation:

`-x -4y = 9`

`x / -9 + (-4/9) y = 1`

`x / (-9) + y / (-9/4) = 1`

It's in the intercept form `x / a + y / b = 1`

`:. color(brown)("x-intercept " = a = -9, " y-intercept " = b = -9/4`
