Question

Find the equation of the line that contains the points (2,1) and (6,3). Write the equation in the form y=mx+b and identify m and b

Answer 1

y=1/2x+0 m=1/2 b=0

Explanation:

You first need to find the slope of this line, the equation for this is.

(y2-y1)/(x2-x1)

In this case it is (3-1)/6-2)

This simplifies to 1/2.

This graph also does not have a +b as when you graph y=1/2x, it already passes through the 2 points shown.
