PLEASE HELP! WILL GIVE BRAINLIST!

write the equation of the line that passes through (0,2) and (2,-4) in slope intercept form.

A. y = -1/3x + 2
B. y = -3x + 2
C. y = -1/3x - 2
D. y = 2x - 3

Answer:

B. y = -3x + 2

Step-by-step explanation:

The equation for slope intercept form is [tex]y=mx+b[/tex]

We need to find the slope and y-intercept.

Let's find the slope first.

Using the slope formula:

[tex]m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  } =\frac{-4-2}{2-0}=\frac{-6}{2}=-3[/tex]

So, the slope of the points (0,2) and (2,-4) is -3.

-3 will replace m.

The Y-intercept, or b, is 2, since (0,2) is on the y-axis.

We end up with: [tex]y=-3x+2[/tex]

Option B is correct since it matches our equation.
