The function f(x) is shown in the graph. what is the equation for f(x)? enter your answer in the box. f (x) = ?

This is a graph of a Line, the equation of a line is in the following form:

  (1)

Where:

is the slope of the line

is the point of intersection of the line with the y-axis

Now, in order to write the equation (1), we have to find the slope first by the following formula:

   (2)

Where and are two points of the line.

In this case:

Substituting:

   (3)

   (4) >>>>This is the slope

Now we have to find the interception with the y-axis, if we look at the graph we will find out the line intercepts with the y-axis in y=-3.

Therefore   (5)

Finally we can write the function:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
