How do you use slope to prove line are parallel

You can tell if two lines are parallel if they have the same slope.  If two lines  do not have the same slope, they are not parallel.

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)

this is false ^.^ lol
