End of The Course Padlet: Algebra and Its Application by Quoc Ngo-Tran https://padlet.com/quancao78/lv17wircmdb1 Made with a wink and a smile en-us 2018-07-25 09:01:12 UTC 2024-05-30 16:16:15 UTC hello@padlet.com Direct inverse: quancao78 https://padlet.com/quancao78/lv17wircmdb1/wish/271084215 y(x) = k x; where k is constant and x is variable

If x increases, y (x) will increase

Application: X(t) = v*t; where v is a average speed and t is time variable. and X(t) is distance travel
If t increases, X(t) will increase.

Direct inverse:

V(t) = X/t  ;  where V(t) is the speed X is known distance and t is a time variable.

If t increases, V(t) will decrease.
If it will take you longer in time to get there, you do not have to drive fast, vice versa.

It is at (0,2) coordinate.]]> 2018-07-25 12:36:18 UTC https://padlet.com/quancao78/lv17wircmdb1/wish/271086092 Finding Slope: quancao78 https://padlet.com/quancao78/lv17wircmdb1/wish/271086162 From the y-intercept, go down  2 unit then go to the right, x-axis 1 until to touch the line.
Slope, m= -2/1 = -2
Go down means negative (-)
Go up means positive (+)
Go to the right means positive (+)

y(x) = mx +b
y(x) = -2x + b
