Question

What are the intercepts of `-3x-7y=5`?

Answer 1

x-intercept: `(-5/3)color(white)("XXXXXX")`y-intercept: `(-5/7)`

Explanation:

The x-intercept is the value of `x` when `y=color(red)(0)`
`color(white)("XXX")-3x-7(color(red)(0))=5`
`color(white)("XXX")rarr x=5/(-3)`

The y-intercept is the value of `y` when `x=color(blue)(0)`
`color(white)("XXX")-3(color(blue)(0))-7y=5`
`color(white)("XXX")rarr y=5/(-7)`
