Answer:
-1,1
Step-by-step explanation:
You'd have to draw a table of x and y values first to be able to graph.
Step 1: Pick any number for x. Let's pick 2.
Step 2: Plug in 2 into the equation: y = 2^2 + 2(2) - 3
Step 3: Solve for y: 4 + 4 - 3 = 5
Step 4: So the point (ordered pair) would be (x, y) ⇒ (2, 5). You can plot that on the graph.
Follow these steps 2 more times to get at least three ordered pairs.
Make sure you have enough points to know where the graph curves, then you can connect the dots and now there you have a graph and chart :)
D. -2/3 because when you do (y2-y1)/(x2-x1) you get -4/6 which simplifies to -2/3
