For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cut point with the y axis.

We look for two points through which the line passes to find the slope:

[tex](x1, y1) = (2,2)\\(x2, y2) = (0, -4)[/tex]

[tex]m = \frac {y2-y1} {x2-x1} = \frac {-4-2} {0-2} = \frac {-6} {- 2} = 3[/tex]

So, the line is:

[tex]y = 3x + b[/tex]

We have "b" replacing any of the points:

[tex]-4 = 3 (0) + b\\-4 = b[/tex]

Finally, the equation is:

[tex]y = 3x-4[/tex]

Answer:

[tex]y = 3x-4[/tex]
