Hello There! :)

Option B

A function must pass the Vertical line test. Draw a line. If it touches the graph more than once, it's a relation. If it touches the graph once, it's a function.

Hope this helps!

I payed for a subsciption my bank has already been debted but it wont let me use it. why not?

ANEK [815]

Answer:

If your payment didn’t go through, change your preferred payment method/add another payment method.

For example, if your preferred payment method is your bank account, we'll always try to use your bank account first for payments. If there's an issue with your bank account, you can change your preferred payment method to a different one, such as a debit or credit card. If you only have a card registered on your account, try adding and confirming a bank account.

Find the equation (in terms of x) of the line through the points (-2,1) and (3,5)

masha68 [24]

Answer:

y = 4/5x +13/5

Step-by-step explanation:

The slope is given by the formula ...

m = (y2 -y1)/(x2 -x1)

m = (5 -1)/(3 -(-2)) = 4/5

The y-intercept is given by the formula ...

b = y -mx . . . . for any point (x, y)

b = 1 -(4/5)(-2) = 1 +8/5 = 13/5 . . . . using the first point

So, the equation is ...

y = mx +b

y = 4/5x +13/5

Additional comment

If you have a bunch of these to do, you may want to make a spreadsheet with the formulas built in. Then you can type in the two points and have it spit out the m and b for your equation. Even if you don't use it to do the work, you can use it to check the work.

Hi,

first you should divide 130 (speed) by 2 (time), then divide 390 by 65 (result of 130 / 2)
