4. Then multiply 14 by 3.14
5. 14 x 3.14 = 43.96
5. There's your answer :)
Hope this helps :)
Answer:
Step-by-step explanation:
1. Put y on the other side - 200x + 500 = y
y= 200x +500
See, this works because -y, when bringing it to another side, you would be adding it. That cancels out the negative, giving you your slope-intercept form. All you have to do is flip it into y=mx + b form, and that's how you get y=200x + 500
