B. contains (-3, -2) and has slope 3

y+2=3(x+3)   y=3x+7

Step-by-step explanation:

First we should use the formula y-y1=m(x-x1)

and x1=-3,y1=-2

so we have the step y+2=3(x+3)

y+2=3x+9   y=3x+7

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°

the correct answer would be the third option
