Answer:
y = 3x + 1
Step-by-step explanation:
First, find slope:


Then, put the equation into point-slope form using the point (1, 4):

where m is the slope
y - 4 = 3(x - 1)
If you want to put this into slope-intercept form, it would be

The y-intercept of the graph equation is (0,-4)
The surface area of the cube is 1536 square feet because (16×16)×6=1536 square feet. Hope it help!
This sets up as a very commonly used proportion.
90 oz / 18.95 = 1 oz / x Cross multiply
90 x = 18.95 Divide by 90
x = 18.95 / 90
x = 0.21 dollars or 21 cents.
So each ounce of shampoo costs 0.21 dollars or 21 cents.
This is a very handy way to check best deals. Stores have trained us for years to believe that the more we buy of a brand, the better the price. It isn't always true. Sometimes buying the smaller quantity is the better deal. There is only one way to be sure and that's to do a proportion like this one.
Try this is an example. The same company makes a smaller container of shampoo of 45 oz for 9.15. How much is 1 oz and which is the better deal? You should get 0.20333 dollars so this is marginally (just) the better deal.
