Answer:
Slope-intercept form: y=-3x-2
Point-slope form: y+5=-3(x-1)
Step-by-step explanation:
Slope-intercept form is y=mx+b
Point-slope form is y-y1=m(x-x1)
The slope is (7-(-5))/(-3-1)=12/-4=-3
Now we solve for b, aka. the y-intercept:
-5=-3(1)+b
-5=-3+b
-2=b
So the equation in slope intercept form is y=-3x-2
As for point-slope form, it's y+5=-3(x-1)
x = {-12, 12}
