The equation for the line is y = 3x - 10.

Solution:

Take two points on the graph of the line.

Let the points are (4, 2) and (2, -4).

Here, [tex]x_1=4, y_1=2, x_2=2, y_2=-4[/tex].

Slope of the line:

[tex]$m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]$m=\frac{-4-2}{2-4}[/tex]

[tex]$m=\frac{-6}{-2}[/tex]

m = 3

Point-slope formula:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-2=3(x-4)[/tex]

y - 2 = 3x - 12

Add 2 on both sides, we get

y = 3x - 10

The equation for the line is y = 3x - 10.
