Which graph represents the solution to the given system? y=4x+4 y=4x-3 if you can answer this without the answers that would be is will not

Hello Jessica! 

Here's a little tip: Cancel out all of the options that do not have a line crossing the y-axis at positive 4 and a line crossing the y-axis at negative 3. That should narrow down the possible answer choices significantly. 

Also take two points, and use the formula  to find out the slope. If both of the lines slope are not 4 (hence m = 4 in the equation), then those are not the correct answers. 

Using both of these tactics, you can solve the problem without visible graphing calculator.
