-5(r+3)

Step 2: Distributive Property (distribute the -5 on the left):

-5r-15

Step 3: Addition Property of Equality (add 7r to both sides):

2r-15

Step 4: Addition Property of Equality (add 15 to both sides):

2r

Step 5: Division Property of Equality (divide both sides by 2):

Select the equation in slope-intercept form that is equivalent to: 4x + 3y = 12
sattari [20]

Answer:

y = -4/3x +4

Step-by-step explanation:

y= mx+b

solve for y.

4x+3y=12

Step 1: Add -4x to both sides.

4x+3y+−4x=12+−4x

3y=−4x+12

Step 2: Divide both sides by 3.

Let's solve for y.

4x+3y=12

Step 1: Add -4x to both sides.

4x+3y+−4x=12+−4x

3y=−4x+12

Step 2: Divide both sides by 3.

3y / 3 =-4x +12 /3

y = -4/3x +4

hopes this helps you out
