Question

Write in point slope form an equation of the line through the pair of points (2,0) and (6,18)

Answer 1

You can write the equation using either point, however first you must find the slope.

y2-y1 divided by x2-x1

(18-0)/(6-2) =4.5

Then put it into the point-slope form

y-y1=m(x-x1) which can be written two ways, once with each point

point (2,0) = y-0=4.5(x-2)

or

point (6,18) = y-18=4.5(x-6)
