Abank asks for a 3-character pin code. the first character is a letter. the other two characters are digits between 0 and 9 inclusive. a how many choices are possible for each character of the code? b what is the total number of 3-character pin codes possible? amy chooses a pin code beginning with the letter a. c how many different pin codes are possible for amy? (5 marks)

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
