Answer:
y=(5/4)x-5/4
Step-by-step explanation:
First we need to find the slope:
![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%7D)
=![\frac{5-0}{5-1}](https://tex.z-dn.net/?f=%5Cfrac%7B5-0%7D%7B5-1%7D)
=5/4
The SLops is 5/4
point-slope forum is
y=(5/4)x-5/4
(i think)
Answer:
![\dfrac{3}{1}=\dfrac{12}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B1%7D%3D%5Cdfrac%7B12%7D%7B4%7D)
Step-by-step explanation:
If you write the proportion as ratios of feet to yards, you have ...
![\dfrac{3\,\text{ft}}{1\,\text{yd}}=\dfrac{12\,\text{ft}}{4\,\text{yd}}\\\\\boxed{\dfrac{3}{1}=\dfrac{12}{4}}\qquad\text{without the units}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%5C%2C%5Ctext%7Bft%7D%7D%7B1%5C%2C%5Ctext%7Byd%7D%7D%3D%5Cdfrac%7B12%5C%2C%5Ctext%7Bft%7D%7D%7B4%5C%2C%5Ctext%7Byd%7D%7D%5C%5C%5C%5C%5Cboxed%7B%5Cdfrac%7B3%7D%7B1%7D%3D%5Cdfrac%7B12%7D%7B4%7D%7D%5Cqquad%5Ctext%7Bwithout%20the%20units%7D)

Please note that a proportion is a true statement. Here, you need only pick the true statement from those offered. For example, here's the first choice written in more readable form:
![\dfrac{12}{1}=\dfrac{4}{12}\qquad\text{FALSE statement}](https://tex.z-dn.net/?f=%5Cdfrac%7B12%7D%7B1%7D%3D%5Cdfrac%7B4%7D%7B12%7D%5Cqquad%5Ctext%7BFALSE%20statement%7D)
Simultaneous equation:
x + y = 13
x - y = 77
