Find the slope of the line 2x+5y=-3.

Question

Find the slope of the line  2x+5y=-3.

kropot72 · Answer

Can you put the equation in standard form?
y = mx + b

yanni · Answer

5y=2x+b

kropot72 · Answer

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?

carniel · Answer

If you always have a hard time trying to find the slope of a line always put it in standard form.

kropot72 · Answer

@yanni can you divide both sides of (5y = -2x -3) by 5?

kropot72 · Answer

$$\frac{5y}{5}=?$$
$$\frac{-2x-3}{5}=?$$

yanni · Answer

-2/5 -3/5

yanni · Answer

y= -2/5x - 3/5

kropot72 · Answer

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?

kropot72 · Answer

The slope is the coefficient of $$-\frac{2}{5}x$$

yanni · Answer

is that the answer

kropot72 · Answer

The slope is $$-\frac{2}{5}$$

yanni · Answer

so the slope of -2/5x

yanni · Answer

i mean the slope of 2x+5y=-3 is -2/5x

kropot72 · Answer

The slope is -2/5 which is the coefficient of $$-\frac{2}{5}x$$
