Graph the function f(x)=−1/4x−2. use the line tool and select two points to graph

The given function is

Notice that this function is linear, that means its graph is a straight line.

To graph a linear funtion you just need to use two coordinates.

For

For

So, the points you need are and .

The image attached shows the graph of the given function, where you can observe the two ponints we used.

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.
