The only visible points in the picture are (-2,0) and (2,0). These are points to be plotted on a grid. The first number is always the x axis (horizontal) . The second number is always the y axis (vertical).
Answer:

Step-by-step explanation:
7. The common difference is 4, so the next term will be 17+4 = 21, and the term after that will be 21+4 = 25. Figuring the next two terms as 21, 25 is sufficient to select the appropriate answer.
8. The table entry (0, 14) tells you only choices G and J are viable. The difference between terms of 22-14 = 8 tells you the appropriate choice is the one with a slope of 8, choice G.
9. In a linear equation, the sum of exponents of the variables in any/every term must not be greater than 1. (All exponents must be integers, as they are here.) Selections A and D have squared terms, so are not linear. Selection C has the product of variables "xy", so is not linear.
In order to solve the problem what you must do is 5- .99 to get 5.01
Substitute 4 for y. Then -3x^2 + 16 = 52.
Solve for x. Subtract 16 from both sides, obtaining -3x^2 = 36.
Divide both sides by -3, obtaining x^2 = -12. This last result makes no sense, as no square of a real number could be negative. Probably this is where you're ":getting a negative answer."
If imaginary answers were allowed, then x = i*√12 = i*2√3 or x = -i*2√3.
x =
