What is the slope of 6x + 3y =15?

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the slope we must first write the equation in the general equation above

That's

6x + 3y = 15

Make y the subject

Send 6x to the other side of the equation

3y = - 6x + 15

Divide both sides by 3

We have

y = - 2x + 5

Comparing with the general equation above

Slope / m = - 2

Hope this helps you

Slope = -2

Step-by-step explanation:

6x + 3y = 15

=> Make the "y" alone.

=> 6x - 6x + 3y = -6x + 15

=> 3y = -6x + 15

=> 3y/3 = -6/3x + 15/3

=> y = -2x + 5

We use a formula => y = mx + b

In the above formula, "m" = slope.

b = y-intercept

So, the slope = -2

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
