1/32(x-4)2-0.5, where x represents the number of seconds since she started the trick and the expression represents the height of the yo-yo i'm meters relative to her right hand over this period of time the height of her right hand relative to sea level can be represented by the expression -1/16(x-7)+12

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

the first one

step-by-step explanation:

just id the test.
