Salesperson would earn $13.6 in commission for selling a microwave oven for $340.  

Step-by-step explanation:

We are given that an appliance salesperson earned $32.80 in commission for selling a refrigerator for $820.

We have to find how much would the salesperson earn in commission for selling a microwave oven for $340.

Firstly, we will the find the rate at which the salesperson gets a commission in % terms.

So, Percentage rate of commission is given by;

Rate of commission=(Commission earned ÷ Selling Price of refrigerator)  100

                                =  =  = 4%

Now, this rate will be used to find the commission earned on selling a microwave oven for $340, i.e;

Therefore, salesperson would earn $13.6 in commission for selling a microwave oven for $340.  

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
