Which graph and equation shows a proportional relationship between x and y? CLEAR CHECK

Line graph with line extending from (0, 0). Next to graph is equation, y = 11.5 x.

Line graph with line not extending from (0, 0) but further down x axis. Next to graph is equation, y = 1.5 x minus 1.5.

Line graph where line does not start at (0, 0) but further up y axis. Equation next to graph, y = 11.5 x + 1.5.

Line graph where line does not start at (0, 0) but runs parallel to x axis, starting at a point on y axis. Equation next to graph is y = 1.5.

the answer

b. they are parallel and will never intersect.

r = 78539458390583095803458309458039485093485 or just 3

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.
