Question 1110432: Draw a triangle with vertices (-6,3), (4,13), and (10,-5). It tells me to find the slope intercept and general form equations for the three sides of the triangle. So I found the slope-intercept form equations for three sides, which are Y=X + 9, Y=-1/2X+0 and y=-3x+25. Does the general form equations just mean standard form? AKA x-y=-9 instead?

Question 1110467: Hello Online Tutors!
Here's my question:
Wendy babysits for the Crest family every Saturday night. She charges $10 per hour for the first 4 hours and 50% more for time after the first 4 hours. She is paid the full hourly rate for any part of an hour she works. Wendy's parents do not let her babysit for more than 8 hours. Draw a graph showing how much money Wendy can earn.
I know that this will be a step function, but I'm not that sure what to take 50% of.
Thank you to anyone that can help!
