What is the equation, in point-slope form, of the line that is
parallel to the given line and passes through the point
(-1, - 1)?
y+1= -3(x+1)
y+1 = 1/3 (x + 1)
y+1=1/3(x + 1)
y+1=3(x + 1)

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

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.
