The equation of a line with gradient m passing through point (xo, yo) is given by:

y - yo = m(x - xo)

The gradient m is calculated:

m = change_in_y/change_in_x

= y1-y0/x1-x0

→ line through points po (2, 3) and p1 (4, -1) has equation:

y - 3 = (-1 - 3)/(4 - 2) (x - 2)

→ y - 3 = -4/2 (x - 2)

→ y - 3 = -2(x - 2)

→ y - 3 = -2x + 4

→ y + 2x = 7
