What is the slope of the line between (1, 5) and (3, 9) is it A, B, C, or D?

A) M=-2

B) M=1/2

C) M=2

D) M=-1/'2

2

Step-by-step explanation

y 1 - y 2 over x 1 - x 2

9-5 over 3-1 equals 4/2 which simplifies to 2

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)
