6. I NEED HELP ASAP IF YOU DON'T KNOW THE ANSWER DON'T PUT ANYTHING!! IT'S NOT D

Write a rule for the linear function shown in the graph.

A. y = 1/4x + 1

B. y = –x + 4

C. y = 4x – 3

D. y = 2x + 5

C. y = 4x - 3

Step-by-step explanation:

Graph the line using the slope and y-intercept, or two points.

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.
