Slope of a Line

Need a quick check on this answer:

3x-5y=8

3x-5y-8=0

3x-8=5y

5y/5 = 3x-8 / 5

y= 3/5x - 8/5

slope = 3/5 ?

if x = 1 and y = -1     3x - 5y = 3 + 5 = 8
if x = 6 and y = 2      3x - 5y = 18 - 10 = 8

x increased by 5, y by 3... slope is indeed 3/5 :)

In y = m*x + c, m is the slope, so just rewrite the equation in that form :-

y = 3/5*x - 8/5

so m = 3/5.

My god,

thats an awful lot of points the auhtor is giving here......Can I have some too??

by the way, your maths is entirely correct and you dont need to show that many steps to prove it.....

I have answered much easier questions than this in other TA's for 500 points. If you know nothing of coordinate geometry this is a hard question.

ee_ai_construct,  I would also say that manav_mathur's comments are off topic as well and should be removed.
