A line passes through the point (-6, 5) and has a slope of -3. Write an equation in slope-intercept form for this line.

y

Step-by-step explanation:

y

=

4

x

−

26

Explanation:

The slope-intercept form of a line is:

y

=

m

x

+

b

where:

m

is the slope of the line

b

is the y-intercept

We are given that

m

=

4

and the line passes through

(

7

,

2

)

.

∴

2

=

4

⋅

Therefore the equation of the line is:

graph{y=4x-26 [-1.254, 11.23, -2.92, 3.323]}

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.
