Answer:

y=-\frac{5}{3}x-2

Step-by-step explanation:

line equation in general y = mx + b

m is the slope, and

b is the y-intercept

3=-3m+b

-7=3m+b

if we plus this two equations

3-7=2b

2b=-4

b=-2

3m=b-3=-5

m=-5/3

So,

y=-\frac{5}{3}x-2

Answer:

y=-\frac{5}{3} x+8

Step-by-step explanation:

Slope= \frac{y_{1}-y_{2}  }{x_{1} -x_{2} }

=\frac{3-(-7)}{-3-3}

=\frac{10}{-6}

=-\frac{5}{3}

So 3=-\frac{5}{3} *(-3)+b, b=8

So y=-\frac{5}{3} x+8
