The equation of a line is defined by: y=mx+b
Step 1: Find the slope (rise over run) so, the rise is 15.7 and the run is 6. 15.7/6=2.62
y=2.62x+b
Step 2: Find the b value (y intercept) - this is where the line goes through the y axis. In this case, it's 15.7
Step 3: add the slope and the b value together - y=2.62x+15.7
Vector
![PQ=(7-5, 3-4)=(2, -1)](https://tex.z-dn.net/?f=PQ%3D%287-5%2C%203-4%29%3D%282%2C%20-1%29)
.
![4RS=4 \cdot (4-8, 1-6) = 4 \cdot (-4, -5) = (-16, -20)](https://tex.z-dn.net/?f=4RS%3D4%20%5Ccdot%20%284-8%2C%201-6%29%20%3D%204%20%5Ccdot%20%28-4%2C%20-5%29%20%3D%20%28-16%2C%20-20%29)
. So the sum is
![(-14, -21)](https://tex.z-dn.net/?f=%28-14%2C%20-21%29)
.
For the second, the magnitude is the square root of the sum of the squares of the components. This is equal to
![\sqrt{(-14)^2+(-21)^2} = \sqrt{637}=7\sqrt{13}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-14%29%5E2%2B%28-21%29%5E2%7D%20%3D%20%5Csqrt%7B637%7D%3D7%5Csqrt%7B13%7D)
