Tell whether this is a linear relationship, is not one, or it’s impossible to tell. john was 4’ when he was 5 months old, 4’2” when he was 6 months old, and 5’ when he was one year old (john is a snake).

Step-by-step explanation:

so John (lol...who names a snake John)ok...so at 5 months he was 4 ft...and at 6 months, he was 4'2means he is growing at a rate of 2 inches per month. So if he continues to grow at 2 inches per month, then this is linear...but if he doesn't, its not linear.

So from 6 months to 1 year, is a period of 6 months...and if he grows at 2 inches per month, in 6 months he should have grown (6 * 2) = 12 inches.

4'2" + 12 inches = 4 ft 14 inches = 5 ft 2 inchesbut he is not 5'2" at age 1, he is only 5 ftso NO, this is NOT linear.

each side has a different length.  

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
