Xavier sells homemade necklaces for a profit of $22 per necklace. He is considering switching to a new type of pendant that will increase his profit, as expressed by the function y = 29x, where x is the number sold and y is the amount of profit. How many more dollars will Xavier earn on each necklace if he switches to the new material? Explain how you found your answer.

7 more dollars per necklace

Step-by-step explanation:

29 is your new unit price subtract it from your old unit price and see your profit increase! (29-22=7)

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
