To find the slope when you are given the graph, you need to find the change of y over the change in x. First, choose two points on the line. I picked (0,2) and (5,-2). By counting boxes, determine the change in y, which is -4. Then determine the change in x which is 5. So your slope is -4/5

Hope this helps

To find the slope of the line you have to find the total rise of the line / the total run of the line. The total rise (4), divided by the total run (-5) equals your slope, -4/5.

Therefore, the slope of the line is -4/5.

Hope this helps, best of luck! :)

Given the question in the image, the following are the solution steps to answer the question

STEP 1: Write the general equation of an ellipse

$\frac{\mleft(x-h\mright)^2}{a^2}+\frac{(y-h)^2}{b^2^{}}=1$

STEP 2: Identify the parameters

the length of the major axis is 2a

the length of the minor axis is 2b

$\begin{gathered} 2a=24,a=\frac{24}{2}=12 \\ 2b=20,b=\frac{20}{2}=10 \end{gathered}$

STEP 3: Get the equation of the ellipse

$\begin{gathered} By\text{ substitution,} \\ \frac{(x-h)^2}{a^2}+\frac{(y-h)^2}{b^2}=1 \\ \frac{(x-0)^2}{12^2}+\frac{(y-0)^2}{10^2}=1=\frac{x^2}{144}+\frac{y^2}{100}=1 \end{gathered}$

STEP 4: Pick the nearest equation from the options,

Hence, the equation of the ellipse in the image is given as:

$\frac{x^2}{144}+\frac{y^2}{95}=1$

Sanjay read 56 pages of his book this weekend. This is 35% of the pages in the book. How many total pages are in the entire book

sukhopar [10]

I don't know if I did this right.
There are 1097.6 pages in the book. I multiplied .35 by 56 and got 19.6. I multiplied 19.6 by 56 and got 1097.6. Therefore, there are 1097.6 pages in the book.
