Answer:

y = -4x+14

Step-by-step explanation:

First find the slope

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

m = (2-10)/(3-1)

   =-8/2

   = -4

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = -4x+b

Substitute a point into the equation

10 = -4(1)+b

Add 4 to each side

14 = b

y = -4x+14

Connie keeps her sports card collection in a 54-page book. Each page has 9 slots for cards.
vesna_86 [32]

Answer:

324 slots.

Step-by-step explanation:

If there is 9 slots per page, and 18 pages in the 54 page book are taken up by football cards, that leaves you with 36 pages left. Again, 9 slots per page, so you multiply 9 x 36 and get 324 slots available for baseball cards.
