Question

sketch a graph of y=f(x)
f(x)=-2x+4

Answer 1

since we have -2 as our slope the rise will be 2 while the run would be 1 as shown: since +4 is our y-int it must cross the y axis at +4

Answer 2

plus its \[\frac{rise}{run}=\frac{-2}{1}\]

Answer 3

sso when i plot them would i be plotting all three

Answer 4

you only plot the equation you are given. the direction of the line is determined by the "sign" and value of the slope

Answer 5

you can plot any point to your choosing as long as it has a slope of -2 and crosses the y axis at +4!

Answer 6

and nincompoop isnt b the y-int?

Answer 7

yes, that's the y-intercept I see I missed it

Answer 8

ok thanks i think i get it
