Determine the slope of the line that passes through the points:

The slope is 2.

Step-by-step explanation:

First find the slope using the formula  (y2 - y1) / (x2 - x1)

(x2, y2) --> (3,11)

(x1, y1) ---> (2,9)

Now you plug in.

(11-9) / (3-2)  =  2 / 1  = 2

The slope is 2.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

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)
