How do you know whether a graph represents a linear relation?
When we choose points on a grpah to substitute their coordinates in an equation, what is an advantage of choosing the points where the graph intersects the axes?

The answer to the first part is if they increase by the same amount each time.

For example 4, 8, 12 (add 4 each time)

As for the second part, so you have the ability to multiply by 0. This can remove, and simplify stuff in the equation

answer: 15

step-by-step explanation:

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)
