An acute angle has a smaller measure than an obtuse angle
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
According to the statement data we have:

Then, the equation is of the form:

We substitute the given point and find "b":

Finally, the equation is of the form:

Answer:

This is the correct answer I hope it helps
I really don't what x equals to but the simplified version of x divided by 8 is x/8.
