I think you have to pay attention in class for this
Answer:
You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear.

f(x)=-x2
Step-by-step explanation:
I believe the first one has a vertex at (-4, 0), the second at (4, 0), the third at (4, -4). The only remaining answer is the last one.
Okay so the equation y two - y one divided by x two - x one will solve this.
what y two means is that you need to plug that in for the second y value. since fractions are in x, y form and you need to start with the second y value,and it would be 3 and following that same idea with y but with the first pair of coordinates it would be 2. so we have done half of this so far by getting 3-2 but we still need to do the same thing we just did BUT for THE X COORDINATES. remember to put the SECOND x coordinate first like we did with the y coordinate. so this portion should be -4 - (-1) all together. never forget if a number has a negative sign! so now the final equation is 3-2 divided by -4 - -1. three minus 2 is 1 and -4 - -1 is -3. now divide your separate answers by each other which is 2 divided by -3 which is -0.666..... you can round that answer or just keep it in fraction form of -2/3 if you’d like.
