Square root it and find x after plug it back in
For this case we have that by definition, the slope of a line is given by:
![m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%20%7By_%20%7B2%7D%20-y_%20%7B1%7D%7D%20%7Bx_%20%7B2%7D%20-x_%20%7B1%7D%7D)
Where:
![(x_ {1}, y_ {1})\\(x_ {2}, y_ {2})](https://tex.z-dn.net/?f=%28x_%20%7B1%7D%2C%20y_%20%7B1%7D%29%5C%5C%28x_%20%7B2%7D%2C%20y_%20%7B2%7D%29)
They are two points through which the line passes.
According to the statement we have two points:
![(x_ {1}, y_ {1}) :( 1,3)\\(x_ {2}, y_ {2}) :( 4,7)](https://tex.z-dn.net/?f=%28x_%20%7B1%7D%2C%20y_%20%7B1%7D%29%20%3A%28%201%2C3%29%5C%5C%28x_%20%7B2%7D%2C%20y_%20%7B2%7D%29%20%3A%28%204%2C7%29)
Substituting we have:
![m = \frac {7-3} {4-1} = \frac {4} {3}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%20%7B7-3%7D%20%7B4-1%7D%20%3D%20%5Cfrac%20%7B4%7D%20%7B3%7D)
Thus, the slope of the line is:
![\frac {4} {3}](https://tex.z-dn.net/?f=%5Cfrac%20%7B4%7D%20%7B3%7D)
Answer:
![\frac {4} {3}](https://tex.z-dn.net/?f=%5Cfrac%20%7B4%7D%20%7B3%7D)
Answer:
Ø
Step-by-step explanation:
Anything that is set to equal <em>x</em><em> </em>is what is known as an undefined <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] because it is a <em>vertical line</em><em>.</em>

Kira runs a total of 144 miles in 9 weeks.
Step-by-step explanation:
Given,
Distance covered on Monday = 2.5 miles
Distance covered on Wednesday = 5.75 miles
Distance covered on Friday = 7.75 miles
Total distance covered per week = 2.5+5.75+7.75 = 16 miles
Total distance in 9 weeks = Distance per week * 9
Total distance in 9 weeks = 16*9 = 144 miles
Kira runs a total of 144 miles in 9 weeks.
