Answer:
1)
[tex]y = \frac{ - 2}{3} x - 6[/tex]
2) slope is -2/3
Explanation:
1)
[tex]10x + 15y = - 90 \\ 15y = - 10x - 90 \\ y = \frac{ - 10}{15} x - \frac{90}{15} \\ y = \frac{ - 2}{3} x - 6 \\ answer[/tex]
2)
when any equation is written as
y = mx + c then m is the slope.
above we have calculated that
[tex]y = \frac{ - 2}{3} x - 6[/tex]
which is in the form of
y = mx + c
where m is -2/3 and c is -6
thus slope is m = -2/3
