How many solutions exist for the system of equations? (Use the graphing calculator tool to help solve the problem.)

–2y + 14x = 4

y = 7x + 14

one solution: approximately (–0.9, 8)
one solution: approximately (8, –0.9)
no solution
infinite number of solutions

Here is a graphing calculator that my teachers use... https://www.desmos.com/calculator plug those equations in and then you can find the solution.

anonymous · Answer

i did, now how do i find out the solution?

k_lynn · Answer

Here's the lines after I put in the equations.  Can you tell me if these lines will ever touch?

anonymous · Answer

yes they will

k_lynn · Answer

look at them again.  THe lines are parallel to each other.  that means they will never touch if they go on forever.  So what does that mean?

anonymous · Answer

there no solution?

k_lynn · Answer

yes! great job!
