Question 131157: I jsut want to be sure I have this problem done right - can you check it for me?
Find the slope and y-intercept of the line 8x + 4y = 24.
8x + 4y = 24
- 8x + 4y = -8x + 24
4/4y = -8/4x + 24/4
y = - 2/1x + 6
Thanks!

8x%2B4y=24 Start with the given equation


4y=24-8x Subtract 8+x from both sides


4y=-8x%2B24 Rearrange the equation


y=%28-8x%2B24%29%2F%284%29 Divide both sides by 4


y=%28-8%2F4%29x%2B%2824%29%2F%284%29 Break up the fraction


y=-2x%2B6 Reduce



So the equation is now in slope-intercept form (y=mx%2Bb) where the slope is m=-2 and the y-intercept is b=6



So you have the correct answer.
