Let's rearrange the equation x + y = 6 to slope-intercept form. Solve for y.
x + y = 6
To get the y variable on the left-hand side alone, subtract x from each side.
x + y - x = 6 - x
y = 6 - x
Rearrange the right-hand side.
y = -x + 6
Now we have it in the slope-intercept form. And to find the slope, we look at the coefficient of x. But there is no coefficient of the -x term!
In all reality, there is. However, it's just 1. -1x is the same thing as -x. We don't show the 1 because it has no effect.
So, -1 is the slope.

Answer: The cost is $0.75 more at the retail store.
Step-by-step explanation: A centimeter ruler can measure the difference.
If you use a drawing with the amount if money represented by the length if the line, one line will be 3.90 cm long. The other will be 4.65. Cm. The difference in length is .75 cm
This is the idea behind number lines.
Answer:
C
Step-by-step explanation:
get the y alone on one side: 2y=8x-12
divide by two on both sides: y=4x-6
