There are 28 students in Mr. Smith's math class. 6/7 of them prefer pizza over cheeseburgers. How many students prefer pizza? Please Help :(

24

Step-by-step explanation:

First you divide 28 by the denominator, 7, which is 4. Then you multiply 4 by the numerator, which is 6, and you get 24

y = 3x - 15

Step-by-step explanation:

slope is m = (Y2 - Y1)/(X2 - X1) = (-6 - -3)/(3 - 4) = -3/-1 = 3

y = 3x + b

plug in either point, say (3, -6):

-6 = 3(3) +b

-6 = 9 + b

-15 = b

So, y = 3x - 15
