Question

(20, 240) and (15,450) lies on line

Answer 1

The points $(20, 240)$ and $(15,450)$ lies on the line given by the following equation:

$\frac{x-15}{20-15}=\frac{y-450}{240-450},$ which is equivalent to the following equations

$\frac{x-15}{5}=\frac{y-450}{-210}$

$y-450=-42(x-15)$

$y=-42x+1080$
