  1. Writing an Equation Using Two Points Goal: to write an equation of a line, in slope intercept form, that passes through two points.

  2. What is the equation for the line that passes through the points (3,4) and (5,8)? Steps: • Calculate slope. • Plug into the slope intercept formula (y=mx+b) • Plug in x and y given in the question into the formula. • Solve for b • Rewrite equation with only slope and y-intercept.
