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

Step-by-step explanation:

we know that

The equation of a line in slope intercept form is

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

substitute the values

step 2

Find the y-intercept b

we have

point (-1,2)

substitute

solve for b

The equation of the line is

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
