Question

What is the slope of the line 2x - 5y = -10?

-5/2
5/2
2/5
-2/5
or none of the above ..

Answer 1

rearrange this to y=mx+b format where m is your slope

Answer 2

even at 2x-5y=-10 you can determine what the slope is. so long as you know the definition of a slope

Answer 3

2x - 5y = -10 -> given
-5y=-2x-10 -> subtract -2x from both sides
y=(2x/5)+2 ->divide both sides by -5

You should know where the slope is! :)

Answer 4

make sure you completely understand y=mx+b; and definition of a slope and different behaviors/properties

Answer 5

thanks guys , but i still dont understand anything about graphing ... lol

Answer 6

have you got a clue what a slope is?

check page 24 and on http://finedrafts.com/files/Larson%20PreCal%208th/Larson%20Precal%20CH1.pdf

but master anything that needs to understand about a slope
