rate of change: they are asking how y is changing with respect to x
Or slope, in other words
I have no idea ;; It's a pretest... Any idea what the answer might be?
look at your graph, u see how if u pick a point on your line it gives u a x value and a y value
Yeah I see..
they are asking you how is the value of the y coodinate changing when you change x
Is it 2? :o
is the y coordinate ever changing?
label a couple of points on that line, and tell me what u notice
uhh i don't.. think so?
i dont know how to do that, im sorry. its very new to me, its a pretest & i dont think we're supposed to exactly know how to do this stuff quite yet..
its okay
so you saw how the y is not changing right
it's also 4am where i am so.. im gonna fall asleep like any second now. i just wann aget the test over with ;;w;
this means the rate of 'change' is 0
Pretests just let you preview what you're going to learn and see what you already know
since there is change in the y value
right,, okay.
there is no*
i see.
to calculate your rate of change you would see the change in y for every change in x
y=mx+b where m is slope. You can easily find the slope on the equation. To find the "how much more" part, you subtract them..
if you have 2 points x1,y1 and x2,y2 (y2-y1)/(x2-x1)
Dan's way is optimal for when your slopes aren't nice and clean like this problem, you should memorize the formula
Okay ^-^
do you have any idea what the answer might be? im really so tired. ive been working for like 3-4 hours straight now and i wanted to get this wrapped up quickly so i dont have to worry about being behind..
The slope of function 1 is 0 because it's a straight line, it's never increasing or decreasing. If y=mx+b where m is your slope is 2 (y=2x+7), you subtract 0 and 2 to get the "how much more" ---- that's if I'm seeing this correctly
0-2? then it would be.. uh, 2? am i right?
Yeah that's what I'm thinking. If I'm wrong someone feel free to jump in, but that's what I think the question is asking
I think it would be 2-0 though
alright !! thank you for your help.,
Good luck on the pre-test, sleep well
thanks ^^
