Answer:
Point slope: y-(-7)=-5(x-(-3))
Slope intercept: y=-5x -22
Standard form: 5x+y=-22
Step-by-step explanation:
Point slope is y-y(1)=m(x-x(1)), so you input the slope and m, which gets you y-(-7)=-5(x-(-3))
Slope intercept is y=mx+b. Since the slope given to us, we find out b with the point using b=y-mx, so b=-7-(-5)(-3), which equals -22, so y=-5x-22
Standard form is Ax+By=C, and A can't be less than 0. So, we have to take the slope intercept form and divide it by -1 to get a positive slope, so the equation ends up being -y=5x+22. Then, you subtract 22 from each side, so -y-22=5x, and then add y to each side to get standard form, which is 5x+y=-22
(hope this helps :P)
