Answer:

A

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-9)/(-3-2)

m=10/-5

m=-2

y=-2x+b

9=-2*-3+b

9=b+6

Answer:

1) x=30 degrees

2)y=20 degrees

1) 3x+2x+1x= 6x (a triangle is normally 180 degrees) 180 divide 6=30 (this is because 6 Xs make up the triangle)

2) 2y+5y+5+y+15= 8y+20, (since a triangle has 180 degrees) 8y+20=180 (-20 from both sides) 8y=160, 160 divide 8=20

(I hope this makes sense)
