The equation of line m, in point-slope form is: y + 3 = 4(x - 1)

Recall:

Slope-intercept form equation is: y = mx + b, where m is slope and b is y-intercept.

Point-slope form equation is: $y - y_1 = m(x - x_1)$ where, $(x_1, y_1)$ is a point and m is the slope.

Equation of line m is y = 4x + 2

Slope of line m is 4

Since line m and line n are parallel, both lines will have the same slope. Therefore, the slope of line n is 4.

To write the equation for line if it contains the point (1, -3), substitute $(x_1, y_1)$ = (1, -3) and m = 4 into $y - y_1 = m(x - x_1)$ :

$y - (-3) = 4(x - 1)\\\\\mathbf{y + 3 = 4(x - 1)}$

Therefore, the equation of line n, in point-slope form is: y + 3 = 4(x - 1)
