Answer:


m=2

Explanation:

- Before beginning, I'm going to show the guideline for slope-intercept form for linear equations:

· Slope-Intercept Form:
y=mx+b


  • m= slope; the rotation of the line

  • b= the line's
    y-intercept; where the line hits the
    y-axis.

· Both
m and
b are constant integers whose value ranges from -∞ ⇒ ∞, all real numbers.

·
y and
x are values that depend on each other's value;
(x,y) is how you would see them written on a number line.

- With this in mind, let's look at our current equation.


6x-3y=54

- It seems that our equation is not in a form that could easily show us what it's rotation is, slope, or where it hits the
y-axis, so we're going to have to rearrange our equation so that it follows the slope-intercept guideline shown above.


6x-3y=54\\6x-3y+(-6x)=54+(-6x)

  • My first step was to move any values that are neither being multiplied nor divided by
    y to the other side of the equation. In this case,
    6x is being added to
    -3y, so by adding the reciprocal of
    6x to both sides, I can move it to the other side.


6x-3y+(-6x)=54+(-6x)\\-3y=-6x+54

  • Now our equation is starting to look somewhat like the guideline for slope-intercept form; all we need to do now is get rid of the
    -3 next to the
    y by dividing.


-3y=-6x+54\\(-3y)/(-3)=(-6x+54)/(-3)\\y=(-6x)/(-3)+(54)/(-3)

  • Almost there. All that's left is simplification and we're done!
    -3 goes into
    -6 two times, and
    -3 goes into
    54 negative eighteen times, so our final, simplified equation is:


y=2x-18

  • By looking at our guideline,
    y=mx+b where
    m is slope and
    b is the
    y-intercept, we can determine that:

The slope of
6x-3y=54 is
2.

Uninterrupted Work:


6x-3y=54\\6x-3y+(-6x)=54+(-6x)\\-3y=-6x+54\\(-3y)/(-3)=(-6x+54)/(-3)\\y=(-6x)/(-3)+(54)/(-3)\\y=2x-18\\m=2
