This one really threw me off...
find the slope of the line containing the points
(x, 2x) and (x + h, 2(x +h))
You have to first find the slope, which is change in y over change in x:
{[2(xh)]2x}/[(x+h)x]
(2x2h2x)/(x+hx)
2h/h
m=2.
i don't have an anwser but i need help with my algebra graphing problems i don't know how anything works and i don't have a lot of time but i just need to know how to find a t chart and solve the equation for y2x=2 so please and yeah if it takes 24 hours online homework help sucks hard
Well, I'm kind of confused by your question, but to get a tchart, hit "STAT". Then hit "Edit". L1 are your xvalues and L2 are your yvalues. To graph y2x=2, first rearrange the equation to y alone:
y=2x2. Then press the "Y=" button on your calculator and type it in. Then press "Graph".
