Step-by-step explanation:

We need to find the slope.  This is the rate of change for a line

Pick two points  (0,1) (1,4)

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

   =(4-1)/(1-0)

   =3/1

The rate of change is 3 dollars per guest

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
