Answer:
![y=-\frac{3}{4}x+1](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B3%7D%7B4%7Dx%2B1)
Step-by-step explanation:
We do not have enough information for slope intercept form. But we can use the point-slope formula to find the information. The formula is
where we substitute a point (x,y) for
.
We have m=-3/4 and (-8, 7). We input m and
.
![y-7=-\frac{3}{4} (x-(-8))\\y-7=-\frac{3}{4} (x+8)](https://tex.z-dn.net/?f=y-7%3D-%5Cfrac%7B3%7D%7B4%7D%20%28x-%28-8%29%29%5C%5Cy-7%3D-%5Cfrac%7B3%7D%7B4%7D%20%28x%2B8%29)
We now simplify the parenthesis and solve for y.
![y-7=-\frac{3}{4} (x+8)\\y-7=-\frac{3}{4}x+-\frac{3}{4} (8)](https://tex.z-dn.net/?f=y-7%3D-%5Cfrac%7B3%7D%7B4%7D%20%28x%2B8%29%5C%5Cy-7%3D-%5Cfrac%7B3%7D%7B4%7Dx%2B-%5Cfrac%7B3%7D%7B4%7D%20%288%29)
We convert 8 into a fraction with 1 as the denoinator.
![y-7=-\frac{3}{4}x+-\frac{3}{4} (\frac{8}{1} )\\y-7=-\frac{3}{4}x+-\frac{24}{4}\\y-7=-\frac{3}{4}x+-6](https://tex.z-dn.net/?f=y-7%3D-%5Cfrac%7B3%7D%7B4%7Dx%2B-%5Cfrac%7B3%7D%7B4%7D%20%28%5Cfrac%7B8%7D%7B1%7D%20%29%5C%5Cy-7%3D-%5Cfrac%7B3%7D%7B4%7Dx%2B-%5Cfrac%7B24%7D%7B4%7D%5C%5Cy-7%3D-%5Cfrac%7B3%7D%7B4%7Dx%2B-6)
We add 7 to both sides to isolate y,
![y-7+7=-\frac{3}{4}x+-6+7\\y=-\frac{3}{4}x+1](https://tex.z-dn.net/?f=y-7%2B7%3D-%5Cfrac%7B3%7D%7B4%7Dx%2B-6%2B7%5C%5Cy%3D-%5Cfrac%7B3%7D%7B4%7Dx%2B1)
This is slope intercept form. The line as slope -3/4 and y-intercept (0,1) or b=1.
Hey there!
Ratios can also be expressed as fractions. The first number will be your numerator while the second number will be your denominator.
![7:3 = \frac{7}{3} =2 \frac{1}{3}](https://tex.z-dn.net/?f=7%3A3%20%3D%20%20%5Cfrac%7B7%7D%7B3%7D%20%3D2%20%5Cfrac%7B1%7D%7B3%7D%20)
![8:4 = \frac{8}{4} = 2](https://tex.z-dn.net/?f=8%3A4%20%3D%20%20%5Cfrac%7B8%7D%7B4%7D%20%3D%202)
![9:5 = \frac{9}{5} = 1 \frac{4}{5}](https://tex.z-dn.net/?f=9%3A5%20%3D%20%20%5Cfrac%7B9%7D%7B5%7D%20%3D%201%20%5Cfrac%7B4%7D%7B5%7D%20)
![2:7 = \frac{2}{7}](https://tex.z-dn.net/?f=2%3A7%20%3D%20%5Cfrac%7B2%7D%7B7%7D%20)
You could then divide these fractions out by dividing the numerator by the denominator to see which is the largest, but we can already tell that 2 1/3, or 7:3, will be the largest, since none of the other fractions are that large.
Hope this helped you out! :-)
