Use the two-point form of an equation of a line:



where and are the coordinates of the given points.

Solve the result for to get the slope-intercept form.

Write an equation of the line containing the points (2, -3) and (4, 5). Write your solution in the standard form of
:::y = mx + b
---------
m = slope = (5--3)/(4-2) = 8/2 = 4
-----
Solve for "b"::
5 = 4*4 + b
b = -11
-----------
Equation:
y = 4x - 11
