1) Let's find the equation of the line. firstly calculating the slope

2) Now that we have found the slope, let's find the linear coefficient

by plugging into the slope-intercept form, one of those points. Usually with the least value.

(3,6)

y=mx+b

6=6(3)+b

6=18+b

6-18=b

b=-12

3) Writing that as a function, we have:

f(x) =6x-12

Write the equation of the line that passes through the pints (3,6) and (5,18) using-example-1
