Without graphing determine whether the lines intersect.

1). \(y = \frac{2}{3} x -1\) and \(y = \frac{3}{4} x – 4\)

2). \(2x-4y=16\) and \(y=0.5x + 4\)

3). \(2x – y = 3\) and \(x + 2y = 4\)

4). \(2x + 4y = 2\) and \(y = -\frac{1}{2} x + 1\)

Go to DESMOS and graph the pairs https://www.desmos.com/calculator

5). Find the solution to each of the systems in 1 – 4.

6). How were the systems different/same?

7). Determine a rule for determining the number of solution to a system.
