Question 245206: You are running in a marathon. You either run 8 miles per hour or walk 4 miles per hour. Write an equation to show the relationship between time ran and time walked during the 26.2 mile course and then graph the equation. I tried to use 8X + 4Y = 26.2 but it did not work out. If you could just help me get the right equation then I can do the graph and the following couple of problems which are all related to this equation.
Thanks in advance for your help!

Question 245519: I need help with this problem:
1)Graph the follwing information in the given coordinate systems. (Be sure to use the information in the eqatuions to help you make your graphs.) Don't forget to draw the lines!
y+6=3/2(x-4)
I just don't understand how I am supposed to graph the equation when it is not in slope intercept form.

Question 245818: Can someone help me.
1. Given the pair of linear equations in two variables:
•Find the x- and y-intercepts (if any) for each line. Show your work.
•Plot those intercepts, and graph the two lines. Submit your graph through the Dropbox.
•Apply elimination or substitution to find the coordinates of the point of intersection (if there are no solutions or infinite solutions, state this). Show your work.

Question 246129: I'm having trouble with this equation?
Y=2x-2
7x+y=7
I have to find the plots and graph, then find the point at which they intercept, if they do?
I'm new at this. Am I supposed to be using a graphing calculator to solve as I don't know how to use it.
When finding plots, is it best to always start with zero as I notice most equations have?
Thank you!
