BRAINLIEST! FOR CORRECCTT ANSWER Choose the slope-intecept form of the equation of the line through the given points.

through: (1,5) and (-3,1)

A) y= 1/2x + 7/2

B) y= 3/2x + 7/2

C) y= 2x + 7/2

D) y= -2x + 7/2

answer: x=60

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.
