I need help

Step-by-step explanation:

1. convert the equation to its y = mx + b format. remember m is the slope (rise/run) and b is the y-intercept.

2. equation given: x + 2y = -6

bring x over to other side

3. now its looks like 2y = -6 - x

to get y by itself we need to divide by 2

4. now equation looks like y = -6/2 -x/2

we can reduce it so the final equation is

5. y = -1/2x - 3

this is in y=mx+b format. now its much easier to graph

6. the slope is -1/2 and the y-intercept is -3. put a point at (0,-3) and use the slope (-1/2) rise over run to get each point.

7. you move to the left because its negative

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

first one because it can't have a fraction in it
