Write the equation of the graph below in slope intercept form.

Question

Write the answer in slope intercept form and please step by step.

(2,1) and (1,3)=

Answer 1

Okay!

First we should fine the slope! The formula to find the slope between two points is

m= y2-y1

x2-x1

You should get a slope of -2!

Omce you get your slope, one way I would find the equation is to plug in one of points into the equation! For example:

Take (2,1)

y= mx+b

1= -2(2)+b

1=-4+b

Add 4 to both -4 and 1, and you should get 5 for B

So it would be

y=-2x+5

Answer 2

Start with two-point form

(y - 1) / (x - 2) = (3 - 1) / (1 - 2)

Can you simplify and convert?
