Unfortunately, due to the quality of your image, it's hard to tell the specifics of questions and answers. However, I can tell you how to solve these and hopefully it helps!
<em>The question asks for the slope of the line:</em>
1. Find the two points of the line that are bolded. It should be given to you. For example, (5,7) and (8,9)
2. The slope formula is: ![\frac{x_{1} -x_{2} }{y_{1} -y_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bx_%7B1%7D%20-x_%7B2%7D%20%7D%7By_%7B1%7D%20-y_%7B2%7D%20%7D)
Using my example of the points, (5,7) and (8,9), 5 could be x1, 7 would be y1, 8 would be x2, and 9 would be y2.
Then, you would plug it in the slope formula:
![\frac{5-8}{7-9}](https://tex.z-dn.net/?f=%5Cfrac%7B5-8%7D%7B7-9%7D)
which equals
![\frac{-3}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B-3%7D%7B-2%7D)
which equals
1.5
<em>Therefore, the slope of the line I gave you is 1.5</em>
I hope this helps you a bit! :)
Answer:
23.7%
Step-by-step explanation:
In order to solve this, we need to find the total expenses as well as the amount of money spent on housing.
The total expenses are simply the sum of the prices of all the items listed under "expenses":
1080 + 385 + 200 + 970 + 230 + 128 + 145 + 210 + 400 + 0 + 410 + 300 + 100 + 0 = $4558
The amount of expenses on housing is $1080. So, divide this by the total and multiply by 100:
(1080 / 4558) * 100 = 23.7%
To start, first convert 7x-2y=3 from standard form to slope intercept form. To do this, first subtract over 7x to get -2y=-7x+3. Then, divide both sides by -2 to get
y=7/2x-3/2
Now that you have this in slope intercept form, take the m value of the equation, 7/2 and find the negative reciprocal of it. This will be the value of the slope of a line perpendicular to 7x-2y=3. Your final answer will be -2/7.
