Graph the line that passes through the points (-4,-6) and (-2,-7) and determine the equation of the line.

Step-by-step explanation:

Step 1. Find the slope (by using the slope-formula)

m = slope

Step 2. Create the equation of a line that has a slope of

Step 3. Find the y-intercept

To do this, use any of the two points and substitute their x and y values

point:

Step 4. Write the equation in Slope-intercept form

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.
