Please find the complete question in the attached file.
In the given image file when we rotate it to 90 degrees clockwise so the value as the rule is
Putting the value in x = 5 and y = 4 then:
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis.
According to the statement data we have:
Thus, the equation is of the form:
We substitute the given point and find the cut-off point:
Finally, the equation is:
We manipulate algebraically to obtain the standard form:
We multiply by 3 on both sides of the equation:
We multiply by -1 on both sides:
