5. Find the slope of the line
PLZZ Help me

y = -2x

Step-by-step explanation

slope intercept form: y = mx + b

m is slope and b is y-intercept

1. lets find y-intercept cuz thats easiest

the line crosses (0,0) at the y-axis so there is no y-intercept

2. to find slope rise/run

we'll start at (0,0) since that's the y-intercept

3. slope is rise/run = -2/1 = -2

it's negative becuase it's going left

_____________________________________________________

another way you can find slope is by the equation y2 - y1/ x2 - x1

take 2 random points from the line, i will use (0,0) and (-2,4)

4 - 0/ -2 - 0 = 4/-2 = -2

slope is -2

pls ask

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
