Question

find the equation of the line joine points (2,2) and (-2,5).
​

Answer 1

Answer:

5x+4y-18=0.

Explanation:

1. the common view of the formula is:

$\frac{x-x_1}{x_2-x_1} =\frac{y-y_1}{y_2-y_1};$

2. according to the formula above the required equation is:

$\frac{x-2}{-2-2} =\frac{y-2}{5-2}; \ <=> \ 5x+4y-18=0.$
