Mathematics: What is the equation of this line in slope-intercept form? y=−3x−1 y = 3x + 1 y=3x−1 y=− 1 3 x−1 idk how to screenshot the graph but here are the points and options (-1,2) and (1,-4) are the points and these are the options y=-3x-1 y=3x+1 y=3x-1 y=-1/3x-1 asap

Who knows bruh i’m ngl don’t even know the answer i’m just doing this cuz it’s mandatory...

y=-3x-1

Step-by-step explanation:

we know that

The equation of a line in slope intercept form is

y=mx+b

where

m is the slope

b is the y-intercept

we have the points

(-1,2) and (1,-4)

step 1

Find the slope m

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{-4-2}{1+1}$

$m=\frac{-6}{2}$

m=-3

step 2

Find the y-intercept b

we have

m=-3

point (-1,2)

substitute

y=mx+b

2=-3(-1)+b

solve for b

2=3+b

b=-1

The equation of the line is

y=-3x-1
