2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
Remember that the slope of a line never changes, so you can choose whatever 2 points you want and you will always get the same slope. Calculate the rise and run (You can draw it on the graph if it helps). The slope is 2/4, which , of course, you can simplify to ½.
