How would I graph a line with a slope of 2/3?
start at the origin as your first point
slope = (change in y value) / change in x value) =2/3
slope = change in y divided by change in x m = 2/3
|dw:1419661753804:dw|
You don't have to start from (0,0). You can start anywhere, but it is just convenient if we did it from (0,0)
just use y = (2/3)*x and pick values for x to get points(x,y)
\(\sf slope = \frac{\Delta y}{\Delta x} = \frac{y_2-y_1}{x_2-x_1} = \frac{2-0}{3-0}=\frac{2}{3} \)
Thank you @nincompoop and @DanJS it seems alot more easier :)
If you want to move the line up or down then use any number b in, y = (2/3)*x + b
welcome
@DanJS don't get too ahead with the point-slope form, she is merely learning slope itself
oh, beg my pard
actually I know all this stuff I just dont know how to graph rise over run which now get :)
>.< rise/run is just a mnemonic devise
I'd be damned if you knew linear equation already and not know how graph a slope
