Answer: I think the answer is b

Step-by-step explanation:

20% off means that there is 80% on which means you pay that 80% so you move the decimal point two spots

80.0% to .80 and multiply store a’s price of 59.99 to get 47.992 round the two in the decimal down making the total price for store a 47.99 and total price for store b 49.99 so store a is the better price by two dollars

a line passes through the point -2 and five and has a slope of 2/3 points A(x,3) and B(-2,y)lie on the line
olasank [31]
A and B lie on the line, yes, but what specifically are you supposed to do?  Looks like your problem statement was cut off before you'd finished typing it in.

You say your line passes thru (-2,5) and has a slope of 2/3?  Then, using the point-slope formula,

y-5 = (2/3)(x+2)  This is the general equation for your line.

Now let's play around with B(-2,y).  Suppose we subst. the x-coordinate of B, which is -2, into the equation   y-5 = (2/3)(x+2); we get y-5 = (2/3)(-2+2) = 0.  This tells us that y must be 5.  But we already knew that!!

So, please review the original problems with its instructions and this discussion and tell me what you need to know from this point on.
