Question

write the equation of the line in slope intecept form that passes through points (7,-1) and (2,8)

Answer 1

First find the slope of these equations by using :
y2-y1/x2-x1 as in (7,-1) (x1,y1) (2,8) (x2,y2)

Using the slope substitute in as "m" in the following equation

(y-y1) = m (x -x1)

Pick any pair of coordinates..Either one as (x1,y1)
and plug into the equation as well..Then Solve =)
