use the graph of the line to answer the questions.
1. what is an equation of the line in point-slope form?
2. how can the point-slope form be written in function notation?

- point-slope form

- function notation

Step-by-step explanation:

The point-slope form of an equation of a line:

m - slope

The formula of a slope:

From the graph we have the points (-2, -1) and (1, 0).

Substitute:

- point-slope form

         use the distributive property

          subtract 1 = 3/3 from both sides

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)
