Answer 1

Answer:

1)

$y = \frac{ - 2}{3} x - 6$

2) slope is -2/3

Explanation:

1)

$10x + 15y = - 90 \\ 15y = - 10x - 90 \\ y = \frac{ - 10}{15} x - \frac{90}{15} \\ y = \frac{ - 2}{3} x - 6 \\ answer$

2)

when any equation is written as

y = mx + c then m is the slope.

above we have calculated that

$y = \frac{ - 2}{3} x - 6$

which is in the form of

y = mx + c

where m is -2/3 and c is -6

thus slope is m = -2/3
