PLEASE HELP!!!!Manuel builds and sells wooden crates. He made this table to show how much his crates cost in dollars. Number of crates: 2 4 6 8 Cost ($): $25 $45 $65 $85Identify the location where Manuel's number of crates equals zero in the format (x,y).
Question
Answer:
So there are two ways I see this problem.First as trick question kinda, due to the fact that it is a word problem and the way it is setup would make me think the answer is 0,0. You don't pay anything for 0 crates.
The other way is by graphing it.
We can take the points and just plug it into [tex]y=xm+b[/tex]
First lets solve for for [tex]m= \frac{y2-y1}{x2-x1} [/tex]
putting in point one and two on the table here gives us 10
The problem here is we don't know the Y intercept which makes finding the equation a tad harder, we are going to have to find to find that as well. It is pretty simple though we can just plug in a random point to make it a solvable problem [tex]25=2*10+b [/tex]. We can then work this out to b = 5
From there we have found the equation with it being [tex]y=x10+5[/tex]. Putting that into our graph gives us a Y intercept of 5 and a X intercept of -0.5.
Sorry if I went a bit far there, hope you can figure the problem with one of those.
