The graph shows a function.
Find the value of b and d.

The required values are b=-6 and d=4

Step-by-step explanation:

The graph corresponds to the function

We are required to find the values of b and d.

They can be found by using two points that are clearly visible on the graph. For example, the points (0,4) and (2,0) belong to the function. Substituting their values in the function:

Simplifying:

4 = d

d = 4

Now use the point (2,0):

Since d=4, and calculating

Simplifying:

Dividing by 4:

The required values are b=-6 and d=4

linear pair postulates

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
