Question

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

Answer 1

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

Answer 2

5y=2x+b

Answer 3

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?

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

-2/5 -3/5

Answer 8

y= -2/5x - 3/5

Answer 9

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?

Answer 10

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

Answer 11

is that the answer

Answer 12

The slope is \[-\frac{2}{5}\]

Answer 13

so the slope of -2/5x

Answer 14

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

Answer 15

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