You can put this solution on YOUR website! 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.
