Question

Medal!!
Which system of equations is represented by the graph?!!!!!

Answer 1

A. y = x plus 4, over x plus 2
y = x + 4

B. y = x plus 4, over x plus 2
y = x − 4

C. y = x minus 4, over x plus 2
y = x + 4

D. y = x minus 4, over x plus 2
y = x − 4

Answer 2

@mathmale ?

Answer 3

ok i am going to give you a site that helps you will that stuff
mathway.com

Answer 4

ok thx, but this is a graph problem, how do I type that in?

Answer 5

on the side of the page will be a tab that says graph so just press it

Answer 6

It doesn't work, they want me to pay:/

Answer 7

thats for you to see the steps did it give you the answer

Answer 8

Let's examine carefully what we're supposed to do in this problem: We are to determine from the graph the equations of (1) the straight line and (2) the hyperbola. we'll compare these equations to the equations in the four given solutions and pick the solution that matches OUR equations. That's it. No point in using one of those fancy online graphing tools here.

Answer 9

Ok:) When I tried solving this one, I just kept getting messed up equations and I don't know how to plug these into a graph:/

Answer 10

Step 1: Look at the straight line in the illustration. Calculate its slope and y-intercept from the graph. Determine which of the four given answers features the same equation of a line.
Step 2: Look at the curved graph in the illustration. This is the graph of
y=1/x after several modifications (that is, reflection of the graph in the y-axis, followed by vertical and horizontal translations. I have no idea whether or not you're familiar with this material, but think this method is the way to go. Compare your equation for the curved graph to those in the four possible answer choices.

Alternatively, graph the 2 equations from each of the 4 answer choices and compare your graphs with the given graph.

sorry, but as much as I'd like to continue helping you, I have to get off my computer.

Answer 11

Note: You don't need to "solve" these equations! All you have to do is to identify which of the given answer choices represent the formulas for the graphs you see in the given diagram.

Answer 12

Ok, like:

for the first option, I tried to factor it down to slope-intercept form. Would I then use the +b on the graph and then use the slope (mx) to go up or down?

Answer 13

Well, if you have a Texas or Casio calculator, you can just plot in the equations, and compare it with your example :)

Answer 14

For example, it's relatively easy to see that the line would have to be
\[y=x-4\]

Answer 15

that eliminates option A and C. Now try plotting the two remaining equations on your calculator and see what fits your graph :)
