Can you put the equation in standard form?
y = mx + b
OpenStudy (yanni):
5y=2x+b
OpenStudy (kropot72):
Not really. First do this:
2x + 5y = -3
Subtract 2x from each side:
2x - 2x + 5y = -3 -2x
5y = -2x -3
Now what do you get when you divide both sides bvy 5?
OpenStudy (carniel):
If you always have a hard time trying to find the slope of a line always put it in standard form.
OpenStudy (kropot72):
@yanni can you divide both sides of (5y = -2x -3) by 5?

\[\frac{5y}{5}=?\]
\[\frac{-2x-3}{5}=?\]
OpenStudy (yanni):
-2/5 -3/5
OpenStudy (yanni):
y= -2/5x - 3/5
OpenStudy (kropot72):
Excellent work! You now have the equation in standard form y = mx + b where m is the slope and b is the intercept on the y axis.
Can you state the value of m now?
OpenStudy (kropot72):
The slope is the coefficient of \[-\frac{2}{5}x\]

is that the answer
OpenStudy (kropot72):
The slope is \[-\frac{2}{5}\]
OpenStudy (yanni):
so the slope of -2/5x
OpenStudy (yanni):
i mean the slope of 2x+5y=-3 is -2/5x
OpenStudy (kropot72):
The slope is -2/5 which is the coefficient of \[-\frac{2}{5}x\]
