Question

Confused on how to write the equation due to the graph having a point at (1,2).

Answer 1

Answer:

The line passes through (1,2) and (4,4)

The equation,

$\frac{y - y1}{x - x1} = \frac{y2 - y1}{x2 - x1}$

$\frac{y - 2}{x - 1} = \frac{4 - 2}{4 - 1} = \frac{2}{3}$

$3(y - 2) = 2(x - 1)$

$= > 3y - 6 = 2x - 2$

$= > 2x - 3y - 2 + 6 = 0$

$= > 2x - 3y + 4 = 0$
