Question

what does the graph of y=-x+2 look like?

Answer 1

First notice that the slope is -1/1 and your starting with your y -intercept of 2
1)Make a point at 2 on the y intercept
2)Then use your slope, go down one and go right one unit..and keep going until you make points long enough to create a line.

Answer 2

It looks like a straight line.

Answer 4

It looks like America's current economic situation.

Answer 5

this is the same as y=-x only with origin (0,2)
since it is y=-x it would it would look like a mirror image of y=x

Answer 6

Isn't wolfram nice? You don't even need teachers anymore ;)

Answer 7

Yea, just students who like to read text to learn.

Answer 8

wolfram always seems to make me more confused. "how did it do that then"?

\begin{array}l\color{red}{\text{W}}\color{orange}{\text{o}}\color{#9c9a2e}{\text{l}}\color{green}{\text{f}}\color{blue}{\text{r}}\color{purple}{\text{a}}\color{purple}{\text{m}}\color{red}{\text{ }}\color{orange}{\text{S}}\color{#9c9a2e}{\text{u}}\color{green}{\text{c}}\color{blue}{\text{k}}\color{purple}{\text{s}}\color{purple}{\text{ }}\color{red}{\text{H}}\color{orange}{\text{a}}\color{#9c9a2e}{\text{r}}\color{green}{\text{d}}\color{blue}{\text{ }}\color{purple}{\text{t}}\color{purple}{\text{i}}\color{red}{\text{m}}\color{orange}{\text{e}}\color{#9c9a2e}{\text{!}}\color{green}{\text{}}\end{array}

Answer 10

oh and by mirror image i mean on the line y=2

Answer 11

I dont support that site..much. Its not helping students..just degrading their brain and performance with given answers. However, for a person who is checking their answers, I guess it could turn out to be very helpful.

Answer 12

integrating can be very confusing though and often i find myself checking answers that are correct but just dont look it on worlfram

Answer 13

If an integral can be expressed using elementary functions and there is a simple process using substitution or integration by parts, wolfram will show you precisely how to get to the end result.

Answer 14

perhaps my answers are wrong then : (
i don't know why but i always seen to struggle much more with complicated integrals than i do with derivatives.

Answer 15

Example:

Click on \(\textbf{show steps}\) and you will see what I mean.

Answer 16

wolfram and similar software does not necessarily degrade brains. It certainly saves time off tedious algorithmic calculations.

if only it displayed such computations for the student...

Answer 17

ahh yes actually that's not too bad, i shut my mouth.

Answer 18

You should realize that many of the mundane computations you will come across in math can be done algorithmically. Not only that but if the programmer so chooses the steps taken to get to the result can be displayed.

Answer 19

I must admit i was thinking more about the nightmares i have with mathcad than wolfram, now i know that not all computers are the same and that some really do have a heart.
