Use the two-point form of an equation of a line to derive an equation for the desired line:
(x\ -\ x_1) )
where )
and )
are the coordinates of the given points.
Once you have made the appropriate substitutions and done the indicated arithmetic, rearrange your equation into slope-intercept (
) form by solving for

What is point-slope form of an equation of the line through the points (–3, 8) and (7, 6). Use (–3, 8) as the point for the equation.
----------------------
slope = (6-8)/(7--3) = -2/10 = -1/5
----
an Form:
8 = (-1/5)(-3)+b
---
b = 8 - 3/5
---
b = 37/5
----
Equation:
y = (-1/5)x+(37/5)
