Question 20396
Yes on number 1
No on number 2, why, because you don't have an equation, you have an expression. To show the slope and y-intercept, you must have an equation, which means 4x+2y must be equal to something.

1)  Rewrite the equation in the slope-intercept form: y = mx + b

6x + 3y = 54  Subtract 6x from both sides of the equation.
3y = -6x + 54 Divide both sides by 3.
y = -2x + 18, compare this with:
y = mx + b

m = -2 This is the slope.
b = 18 This is the y-intercept.
