Aline has a slope of 1/7 and passes through the point (14,2). what is its equation in slope-intercept form?

y=(1/7)x

Step-by-step explanation:

y= mx+b

m=1/7

to find b:

y=(1/7)x +b

you have point (14,2)-->x=14, y=2

2=(1/7)times14 +b, b=0 > y=(1/7)x+0

correct answer:

b.(19,-2)

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.
