What’s the answer to this ?

4th one

Step-by-step explanation:

if you add them

The graph in the attached figure

Step-by-step explanation:

Let

x ---> the number of hours spent on the client’s case each week

f(x) ---->  the total charge that week in hundreds of dollars

we have

distribute

This is the equation of the line in slope intercept form

where

The slope or unit rate is

The y-intercept or initial value is

To graph the line we need minimum two points

Find the x-intercept

For f(x)=0

The x-intercept is the point (-2,0)

so

we have

the points (-2,0) and (0,8)

To graph the line, plot the intercepts, connect them and join the points

The graph in the attached figure

Remember that the value of x and the value of f(x) cannot be a negative number
