Graph `3y=-9x+6` What is the slope?
Answers -9

-3

Answer 1

• The slope is -3.

Explanation:

Let's simplify the equation.

We know that:

• Formula = y = mx + b
• m = slope
• b = y-intercept

Work:

• 3y = -9x + 6
• => y = -9x/3 + 6/3
• => y = -3x + 2

Let's compare the formula with our resulting equation.

• => (y = -3x + 2) = (y = mx + b)
• => -3x = mx
• => -3 = m

Hence, the slope is -3.

Hoped this helped.

Answer 2

First, we just need y and not 3y. So, we divide both sides by 3.

y = -3x + 2

This equation is shown as y = mx + y-intercept, m being the gradient or slope so -3 is the slope.
