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

Point slope form :

Function notation :

Step-by-step explanation:

If a line passes through two points and , then the point slope form of line is

Where, m is slope.

From the given graph it is clear that he line passes through the points (-2,-1) and (1,0). Slope of the line is

The point is (1,0) and slope is 1/3. So, the point slope form of the line is

Therefore the point slope form is .

Replace y by f(x) to write the equation in function notation.

Therefore the function notation is .

- 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

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
