The value of a professional basketball player's autograph rose 20% in the last year. it is now worth $252.00. what was it worth a year ago?

The worth of the player a year ago = $210

Step-by-step explanation:

let the previous year worth be $ y

If we add 20% of y to y we will get the current year worth, which is $252 .

20/100 × y + y = 252

1/5y + y = 252

0.2y + y = 252

1.2y = 252

divide both sides by 1.2

y = 252/1.2

y = $210

The worth a year ago is $210

you should at least use a calculater

step-by-step explanation:

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
