Answer:
Step-by-step explanation:
step 1
Find the slope
The formula to calculate the slope between two points is equal to
we have
the points (−1,12) and (1,2)
substitute
step 2
we know that
The equation of the line in slope intercept form is equl to
where
m is the slope
b is the y-intercept
we have
substitute in the linear equation and solve for b
therefore
The age of the giraffe when he is 15 feet tall be 1 year 1 month and 16 days.
<h3>What is fraction?</h3>
A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Giraffe height = 6 feet
Height grew in 7 months= 1.75 feet
Giraffe's height in 7 month = 7.75 feet
Giraffe's height, 1 feet= month
= 0.9032 months
Giraffe's height, 15 feet= 0.9032 x 15 month
= 13.548 month
= 13 months 16 days approx.
= 1 year 1 month 16 days
Hence, the age of giraffe will be 1 year, 1 month and 16 days
