A model giraffe has a scale of 1 in : 3 ft. If the real giraffe is 12 ft tall, then how tall is the model giraffe?

Let h = height of giraffe

1/3 = h/12

3h = 12

h = 12/3

h = 4 feet

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

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
