Question

Write an equation in slope-intercept form for the line passing through (–1, 10) and (5, 8).

Answer 1

first find the equation of the line
if a line passes through (x1,y1) and (x1,y2) then equation of the line is
(x-x1)/(y-y1)=(x1-x2)/(y1-y2)

Answer 2

so equation is
(x+1)/(y-10)=(-1-5)/(10-8)
