amistre64 · Answer

what is the slope intercept form of a line in general?

anonymous · Answer

i dont know.. this is all it says on my summer math packet

immanuelv · Answer

slope for #1 is 1

anonymous · Answer

the slope is whatever is in front of the x so the first is 1 the second is 1/2 and the third u need to make y=mx+b so y=-2x+3 so the last is -3

amistre64 · Answer

im pretty sure they give you more than that in the material ....

anonymous · Answer

the y intercept is the last number so 1 -2 3

amistre64 · Answer

how would they expect you to answer the questions if they dont provide the basis for it?

anonymous · Answer

they didnt. its my high school summer math packet and thats all it says on the directions :(

anonymous · Answer

in y=mx+b the m is slope and b is y intercept

amistre64 · Answer

well, if you want, we could cycle thru the many "forms" that an equation of a line makes ...

anonymous · Answer

so its just that easy? i just need to look at the equation not even try to do any work?

immanuelv · Answer

anything infront of "X" is the slope...

amistre64 · Answer

the work is to recognize the general form of the equation and pick out the important parts :)

amistre64 · Answer

"anything in front of x" is not quite right; you have to have the proper form first

amistre64 · Answer

3x =4y -7 ; the slope is not 3 ....

anonymous · Answer

no because its not y=mx+b that's standard form

amistre64 · Answer

exactly :)

anonymous · Answer

so whats the right answer? is superjew right?

anonymous · Answer

yes im right

anonymous · Answer

ok thank you so much! :)
