Answer:
is it asking for linear functions
Answer:
y = (1/2)x - 3 Answer A is closest.
Step-by-step explanation:
Two points on the line are (0, -3) and (4, -1). Notice that I've intentionally chosen "nice" points whose coordinates are integers; this makes the math easier. The point (1, -5/2) is also on the line if you want to use it, but the math's a bit more complicated.
Going from (0, -3) to (4, -1), x increases by 4 and y increases by 2. Hence, the slope of this line is m = rise / run = 2/4, or m = 1/2.
The slope-intercept formula for the equation of a straight line is the most convenient to use here, since we can tell immediately from the graph that the y-intercept is (0, -3):
y = (1/2)x - 3
Answer A should be y = (1/2)x - 3 for improved legibility. 1 2 x is not correct as a way to express (1/2)x.

Answer:
The answer is D
Step-by-step explanation:
Answer:
Option B is correct.
Step-by-step explanation:
Recall that the domain is the set of (unique) inputs and the range is the set of outputs (which do not have to be unique).
The set of inputs of the given relation is {-1, 9, -10, 1}, and this set is also found in Option B. The set out outputs is {7, 2, 6, -6|, which is in Option B.
