And please, next time give the problem fully.
Answer:
1a. y-intercept: 12
1b. slope: -3/2
1c. equation: y = -3/2x +12
2a. y-intercept: -9
2b. slope: 2
2c. equation: y = 2x -9
Step-by-step explanation:
<h3>1.</h3>
A) We observe the pattern to be <em>x-values in the table increase by 2, while y-values in the table decrease by 3</em>. We notice the first x-value is 2, so extending the table upward to x=0 would tell us the y-intercept. That is, adding 3 to the first y-value will give the y-intercept as (x, y) = (0, 12).
B) We have already observed that the "rise" (change in y) is -3 for each "run" (change in x) of 2. The slope is the ratio of these changes:
slope = m = rise/run = -3/2
C) From the above, we know that m=-3/2 and b=12. Putting these values into the equation for the line gives ...
y = -3/2x +12

<h3>2.</h3>
A) We observe the pattern to be <em>y-values increase by 2 while x-values increase by 1</em>. As before, we can find the point that would go before the first one shown in the table. It will have an x-value of 0 and a y-value of -9.
the y-intercept is -9
the slope is 2/1 = 2
the equation is y = 2x -9
The red container in set 2 should be 16 ft^3

Answer:
Option C 67 upto 70
Step-by-step explanation:
Given that heights of college women" recorded to the nearest inch: the first two class midpoints are 62.5" and 65.5".
This explains that each class width=Difference between mid values of successive classes ![65.5-62.5 = 3](https://tex.z-dn.net/?f=65.5-62.5%20%3D%203)
Also next class will have midvalue as ![65.5+3 = 68.5](https://tex.z-dn.net/?f=65.5%2B3%20%3D%2068.5)
So next class has mid value as 68.5 and width as 3
i.e. 1.5 each side should be given
So class interval = ![(68.5-1.5, 68.5+1.5)\\=(67, 70)](https://tex.z-dn.net/?f=%2868.5-1.5%2C%2068.5%2B1.5%29%5C%5C%3D%2867%2C%2070%29)
Option c
