Question

A line passes through (2, –1) and (8, 4).Write an equation for the line in point-slope form.
Rewrite the equation in standard form using integers.

Answer 1

first find slope (m).
m=y2−y1x2−x1

equation of line:
(y−y1)=m(x−x1)

assume:
(x1,y1)
(2,-1)
........................................
(x2,y2)
(8,4)
