Answer:
A
Step-by-step explanation:
To find the slope of a line, we can use the slope formula:
So, we will need to choose two points from the graph. Any two points will work.
Let’s choose (0, -1) and (1, 2).
So, we will let (0, -1) be (x₁, y₁) and (1, 2) be (x₂, y₂). Substitute these values into the slope formula:
Evaluate:
Therefore, the slope of the line is 3.
Hence, our answer is A.
9 gallons of gasoline would cost 30.33
9 x 3.37=30.33 you just have to multiply the gas by the gallons and then that will give you your answer

14x1/3=14/3 14/3=4 2/3 so the answer is 4 hours and 40 minutes
Answer:
84%
Step-by-step explanation:
What we must do is calculate the z value for each value and thus find what percentage each represents and the subtraction would be the percentage between those two values.
We have that z is equal to:
z = (x - m) / (sd)
x is the value to evaluate, m the mean, sd the standard deviation
So for 190000 we have:
z = (190000 - 200000) / (10000)
z = -1
and this value represents 0.1587
for 230000 we have:
z = (230000 - 200000) / (10000)
z = 3
and this value represents 0.9987
we subtract:
0.9987 - 0.1587 = 0.84
Which means that it represents 84% of the houses
