Really need help on this please

age is going to be the bottom axis and sleep is the left

put your finger on the age given, and move it up until you hit the amount of sleep an the y axis(or left).

so for age 1 the point would be at (1,13) age 2 (2,11) and so on

x+14

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)
