Answer:

$y - 4x = 1$

Step-by-step explanation:

Given

$(x_1,y_1) = (1,5)$

$(x_2,y_2) = (3,13)$

Required

The equation of the line

Back up:

First, calculate the slope(m)

$m = \frac{y_2 -y_1}{x_2 - x_1}$

$m = \frac{13-5}{3-1}$

$m = \frac{8}{2}$

$m = 4$

Calculate the area using:

$y - y_1 = m(x - x_1)$

$y- 5 = 4(x - 1)$

$y- 5 = 4x - 4$

Collect Like Terms

$y - 4x = 5 - 4$

$y - 4x = 1$
