<PRE><B>Question 651290</B>
what is the slope of 3x+4y=60


3x + 4y = 60

Subtract 3x from each side of the equation.

3x + 4y - 3x = 60 - 3x

Combine like terms:

3x - 3x = 0

4y = 60 - 3x or

4y = -3x + 60

Divide each item by 4

4y/4 = -3x/4 + 60/4

y = -3x/4 + 15

The Slope Intercept Formula:

y = mx + b

m = slope

b = y-intercept

Therefore:

The Slope of the above straight line graph is:

-3/4
