How do I give the slope for this equation?
\[y = \frac{- 3 }{2 }x +4\] The y intercept is 4, so how do I find the slope?
the slope of y=mx+c is just the 'm' so, what about your equation ?
so, \[\frac{ -3 }{ 2 }\] is m?
coorect! thats your slope :)
would it look like this on the graph?
|dw:1379462837246:dw|
thats just a point, you need to graph the line, right ?
yes
do you know how to ? have u graphed the line before ?
you have y-intercept as 4 , so (0,4) can u find x-intercept ?? hint: put y=0 in the equation
No, I'm afraid not
to find x-intercept put y=0 in the equation what u get ?
\[\frac{ -3 }{ 2 }x+4\] Then, -3 divided by 2, so I get -1.5 + 4. So... 2.5?
0 = -3/2 x +4 so, 3/2 x = 4 x= 4*2/3 = 8/3 right ?
Wait, how did -3 turn into a positive?
by adding -3/2x on both sides so, in right side ,0 +4, left side +3/2x
oh, I get it now.
