The slope of the line below is-3. Which of the following is the point-slope form of the line?
O A. y + 2 = 3(x - 2)
O B. y-2 = -3(x+2)
O C. y-2 = 3(x+2)
O D. y + 2 =-3(x-2)

you need to show the graph

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
