The way you wrote the question was a bit confusing. Also, there are two variables here. To find the one variable (the number of rolls of wrapping paper) we need to find the number of packages.

Find and interpret the slope of the line containing the given points. (12,4) and (10,10)
MAVERICK [17]

Answer:

3/-1

Step-by-step explanation:

The slope is 3/-1 (Rise 3 on the y axis, run to the negatives by 1 on the x axis)

To find the slope of two points, use the formula of y2-y1/x2-x1 (For example, with this equation it would be 10-4/10-12)

I'm not sure what it means to interpret the slope, but hopefully this helped you!

Heather has $500 in her savings account. She withdraws $20 per week for gas. Write an equation Heather can use to see how many w
tatuchka [14]
Since she has a base amount of $500, that will be your y-intercept. 20 is going to be your slope, and since she's withdrawing it, it will be -20. Here's how the equation would be set up (in y = mx + b):

-20x + 500 = 220

*Subtract 500 from both sides*

-20x = -280

*Divide both sides by -20*

x = 14.

Therefore, it will take 14 weeks.
