Would be great if i got some on this!

i already know the first part i just need on the second part.

Step-by-step explanation:

when n=1 then the exponent becomes 1-1=0 and anything raised to the 0 exponent is 1

therefore a(1)= 1/2

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

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
