Write an equation of a line that passes through (-12, -14) with slope 6.

The slope intercept form of a line is y = mx + b

Plug in the slope, 6, into m.

Rewrite the equation;

Plug in your point coordinate, (x, y) ⇒ (-12, -14) into the equation.

Solve for b to find the y-intercept.

Your new equation (your answer) is y = 6x + 58.

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.
