Write an equation of the line that passes through (-3, 10) and is parallel to the line y=-2x-9

y = -2x+4

Step-by-step explanation:

y = -2x-9

We want a line that is parallel so it has the same slope

The slope is -2

We will use the slope intercept form of a line

y = mx+b

y = -2x+b

Substitute the point into the equation

10 = -2(-3)+b

10 = 6+b

10-6 =b

4=b

Substituting into the equation

y = -2x+4

y = -2x + 4

Step-by-step explanation

Parallel lines have the same slope,

So the slope is -2

y = -2x + c

10 = -2(-3) + c

c = 4

y = -2x + 4

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

-2 is the right
