Complete the equation of the line whose y-intercept is (0,-1) and slope is 4.
y=

y = 4x - 1

Step-by-step explanation:

Just plug it into slope intercept form which is y = mx + b

hope this helped!

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

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.
