Question

Use and write different forms of linear equations, such as slope-intercept, point-slope, or standard form. Be sure you are able to identify which form is best in specific situations.

Answer 1

someone please help

Answer 2

i will reward medals.

Answer 3

slope-intercept form: y = mx + b
when m = slope and b = y-intercept

point slope form: y - y1 = m(x - x1)
when m = slope and given the point (x1, y1)

standard form: ax + by = c
when a b and c are integers

Answer 4

so is that a forumula?

Answer 5

oh i have to have a situation for one of them.

Answer 6

those are the formulas for which you would plug into :)

so for example
if given slope is 2 and y-intercept is (0, 3)
then you can use slope-intercept form: y = mx + b
plug in slope = m = 2 and b = y-intercept = 3
so for that example the equation would be y = 2x + 3

Answer 7

uh i need a real life situation with this.

Answer 8

jigglypuff?

Answer 9

I'm not too good at thinking up this sort of stuff ;)

number of hours past: 0, 1, 2, 3
number of files copied: 5, 8, 11, 14
for this situation, every 1 hour, 3 copies are made
and when it was 0 hours, there had been 5 copies
therefore m = 3 and b = 5
so equation would be y = 3x + 5

Answer 10

ok that works thank you so much! :-)

Answer 11

glad I could help :)
