List the ordered pairs in this table:
x -3 0 2
y 2 4 5
{(-3,2), (0,4), (2,5)}
300
The point (0,3) is a called a _.
y-intercept
300
Is this a good line of best fit and why?
No, it is not because it's too high - it's not in the center/middle of the data.
400
Why can not you not use the product rule in 42 + 43?
Because the bases are being added, not multiplied.
400
How many solutions are there to the following equation?
6x + 7 = 2x + 4x + 7
Infinitely many solutions
400
What is the domain of this set?
x -3 0 2
y 2 4 5
D = {-3, 0, 2}
400
What is the slope of the following line?
y = -2x - 4
-2
400
What's the correlation of the following situation?
As snowfall increases, there are fewer people driving on the roads.
Negative correlation (as x goes up, y goes down)
500
Which rule would you use for the problem 75/72?
The Quotient (of Powers) Rule
500
Is 3 a solution to this equation and why?
4x - 2 = 4x + 5
No, because -2 does not equal 5, so there is no solution (no number, including 3, is a solution).
500
What is a point that would make this set of values no longer a function?
{(-2,4), (1,6), (3,7)}
Any point that either:
Has an x-coordinate of -2 but not a y-coordinate of 4
Has an x-coordinate of 1, but not a y-coordinate of 6
Has an x-coordinate of 3, but not a y-coordinate of 7
500
