Answer:
Rachel's conclusion is valid. The ratios for green beans to total students for the survey and the school form a proportion.
Step-by-step explanation:
Solve using proportions. The format should be "Green beans" on the top, and "Total students" on the bottom.
Simplify the first numerator
Find the <u>common ratio</u>
The common ratio is the number you multiply by to get from the top left to top right. It's the same number the you can multiply the bottom left number by to get the bottom right.
<u>Divide the right side by the left side to find the ratio.</u>
Top: ratio = 240/10 = 24
Bottom: ratio = 600/25 = 24
Since the ratios are <u>the same</u>, they are <u>common</u>.
Therefore the proportion is correct, and Rachel's conclusion is valid.

Answer:
B
Step-by-step explanation:
The general equation of a straight line can be represented as;
y = mx + b
where m is slope
If two lines are perpendicular, the product of their slopes will be -1
So since the slope of the first line is 1, then the slope of the second line will be -1
Out of all the options, only have its slope as -1 and this y = -x + 6 and this is our answer
