How do I find an equation that passes through two given points?

first of all find the slpoe using the formula
(y2-y1)/(x2-x1)
now use the formula for equation as
y=mx

Equation of a straight line passing through (x1, y1) and (x2, y2) is

(y - y1)/(x - x1) = (y1 -y2)/(x1 - x2)

the complete equation is y=mx+b

m = the slope
b = the y intercept
