Answer: the slope is 1 up or down and one left or right (if you go down its a left if you go up its a right)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
point-slope form is y-y1=m(x-x1) . since the slope is 2 and not -2, you can automatically eliminate choices A and C. since the y-value in the point, (1,-1), is -1, you will add it to y because you are subtracting a negative. (- - = +) therefore, the final equation, in point-slope form, is y+1=2(x-1), or answer choice D.
Answer: The answer is letter B "No; a range value has two domain values".
For a relationship to be a function, there must be a one-to-one correspondence between the x and y values. For every value of x, there must be only one value for y. So the first set is a function and the second set is not.
Answer:
No; a range value has two domain values.
Step-by-step explanation:
Output has to be unique for all inputs.
Output for -2 is not unique
Step-by-step explanation: It is either B or C
Since
x = −
2
produces
y = 1
and
y = 2
