To convert an equation into y = mx + b format, obviously we will need to isolate the y variable on the left side of the equation. We have the equation 6x + 5y = -15 to work with. The first step we will take in converting this equation is to shift the x value to the opposite side. We can do this by subtracting 6x from both sides.

6x + 5y = -15

6x - 6x + 5y = -15 - 6x

Now, we will reorder our terms, since the mx value must come before the b value.
We will also combine any like terms so that our equation is simplified.

6x - 6x + 5y = -15 - 6x

5y = -6x - 15

Now, all we must do is divide both sides of the equation by 5 to isolate the y variable.

5y / 5 = (-6x - 15) / 5

y = $\frac{-6}{5}$ x - 3

So there we have it.

6x + 5y = -15 in slope intercept form is y = $\frac{-6}{5}$ x - 3.
Hope that helped! =)

6x+5y=-15
solve for y basically
subtract 6x from both sides
5y=-6x-15
divide both sides by 5
y=-6/5x-3

The sum of the squares of 2 consecutive negative integers is 41. What are the numbers? Which of the following equations is the r

VARVARA [1.3K]

Answer:
The two numbers are -5 and -4

Explanation:
Assume that the first number is x and that the second number is x+1.
We know that the sum of their squares is 41. This means that:
x² + (x+1)² = 41

We will expand the brackets and factorize to get the value of x as follows:
x² + (x+1)² = 41
x² + x² + 2x + 1 = 41
2x² + 2x + 1 - 41 = 0
2x² + 2x - 40 = 0
We can divide all terms by 2 to simplify the equation:
x² + x - 20 = 0 ..........> equation required in part II

Now, we can factorize this equation to get the values of x:
x² + x - 20 = 0
(x-4)(x+5) = 0
either x = 4 .........> rejected because we know that x should be negative
or x = -5 ...........> accepted

Based on the above calculations, the two numbers are -5 and -4

Hope this helps :)
