Answer 1

See below.

Explanation:

`Ax+By=C`

We know the x axis intercept occurs where `y=0`

`Ax+B(0)=C`

`x=C/A`

We are told `C` is negative and `A` is positive,so:

`C/A` is negative. i.e. `(-)/(+)=-`

`bbx` intercept is negative.

We now the y axis intercept occurs where `x=0`

`A(0)+By=C`

`y=C/B`

We are told `B` and `C` are negative, so:

`C/B` is positive. i.e `(-)/(-)=+`

`bby` axis intercept is positive
