Step 1
<u>Find the equation of the line</u>
we know that
the equation of the line in the slope-intercept form is equal to

where
m is the slope
b is the y-intercept
in this problem we have

substitute the values
Step 2
<u>identify the coordinates of four points on the line</u>
we know that
if a point belongs to the line, then the point must satisfy the equation of the line.
Let's assume different values of x and then with the equation we will calculate the value of y
<u>case a)</u> For 
Substitute the value of x in the equation and find the value of y
The point A is 
<u>case b)</u> For 
Substitute the value of x in the equation and find the value of y
The point B is 
<u>case c)</u> For 
Substitute the value of x in the equation and find the value of y
The point C is 
<u>case d)</u> For 
Substitute the value of x in the equation and find the value of y
The point D is
