Answer 3

for 2) plot the points

in order to prove that the triangle is (or isn't) a right triangle, there must be two lines where the slopes are perpendicular (or in other words, opposite-reciprocals)

Answer 4

3)

3x + y = -8

we can re-write this as

y = -3x - 8

if the slope is -3 the perpendicular slope must be the opposite-reciprocal, or in other words, 1/3

you are given the point (-3,1)

so plugging this into y = mx + b form

1 = (1/3)(-3) + b

solve for b, then re-write the equation in y = mx + b form
