Question

What is the slope of 1.5x+4.5y=18 ,and how do you know?​

Answer 1

Answer: the slope is -0.33... The does means that 3 is repeating.

Step-by-step explanation:

First we will convert the equation into slope intercept form, which is the same way of solving for y in the equation.

1.5x + 4.5y = 18 Solve for y by first subtracting 1.5x from both sides

-1.5x -1.5x

4.5y = 18 - 1.5x Now divide both sides by 4.5

y= 4- 0.33x

y= -0.33x + 4 Now the slope is the coefficient of the variable x which is the number that comes after the variable.

In this case, the slope is -0.33...

Answer 2

m=-1/3

Explanation:

The slope of this line is m=-1/3 because if you use the slope-intercept formula, y=mx+b, m is the slope. If you take this equation and plot two points on a line that has this equation, the slope will be negative if the line forms an obtuse angle on the 0 line. In this case, m=-1/3 as the line goes back 1/3 unit for every unit in this equation. Hope it helps!
