# What is the linear equation for a line that passes through points (2,4) and (1,0)?

May 7, 2018

y = 4x - 4

#### Explanation:

$\frac{{Y}_{2} - {Y}_{1}}{{X}_{2} - {X}_{1}}$ = $m$, the slope

(2, 4) $\left({X}_{1} , {Y}_{1}\right)$
(1, 0) $\left({X}_{2} , {Y}_{2}\right)$
$\frac{0 - 4}{1 - 2}$ = $m$
