Could some me with this math question

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

Where:

m: It's the slope

b: It is the cut-off point with the y axis

To find the slope we look for two points through which the line passes:

We have to:

Thus, the slope is:

We have then:

Substituting a point in the equation to find b:

Finally, the equation is:

Option D
