Question 218072
Find the x and y intercepts of the graph of -2x-4y=-20


Step 1.  The intercepts occur when the one of the coordinates is zero.  The y-intercept is when x=0 or at point (0,b) where b is the y-intercept.  The x-intercept is when y=0 or at point (a,0) where a is the x-intercept.


Step 2.  So let x=0, then -2*0-4y-20 or 4y=20 or y=5 after dividing by 4 to both sides.  Therefore, the y-intercept is 5.


Step 3.  So let y=0, then -2x-4*0-20 or 2x=20 or x=10 after dividing by 10 to both sides.  Therefore, the x-intercept is 10.


Step 4.  ANSWER:  The x-intercept is 10 and the y-intercept is 5.


I hope the above steps and explanation were helpful.
