Type of slope is if it is negative or positive so looking from left to right does the line go down or up. For 1 it is positive but for 3 it is a negative slope. And triangle y(delta y)/ delta x is basically y2-y1/x2-x1. So pick two point and plug In the numbers. So slope of number one is 1/2 ( you could also count the rise over run from one point to another too)

Answer:
v = 6.32 m/s
Step-by-step explanation:
<u>Given Data:</u>
Mass = m = 40 kg
Kinetic Energy = KE = 800 J
<u>Required:</u>
Speed = v = ?
<u>Formula:</u>
![\displaystyle KE = \frac{1}{2} mv^2](https://tex.z-dn.net/?f=%5Cdisplaystyle%20KE%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20mv%5E2)
<u>Solution:</u>
Rearrange the formula for speed
![\displaystyle v =\sqrt{\frac{2KE}{m} } \\\\Put \ values\\\\v = \sqrt{\frac{2(800)}{40} } \\\\v = \sqrt{2(20) } \\\\v = \sqrt{40} \\\\\boxed{v = 6.32 \ m/s}\\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20v%20%3D%5Csqrt%7B%5Cfrac%7B2KE%7D%7Bm%7D%20%7D%20%5C%5C%5C%5CPut%20%5C%20values%5C%5C%5C%5Cv%20%3D%20%5Csqrt%7B%5Cfrac%7B2%28800%29%7D%7B40%7D%20%7D%20%5C%5C%5C%5Cv%20%3D%20%5Csqrt%7B2%2820%29%20%7D%20%5C%5C%5C%5Cv%20%3D%20%5Csqrt%7B40%7D%20%5C%5C%5C%5C%5Cboxed%7Bv%20%3D%206.32%20%5C%20m%2Fs%7D%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
