Janelle built a catapult to launch snowballs at her brother for their epic snowball fight. She wants to figure out how long her snowballs will be in the air for before they land, so she develops the quadratic
expression below in which "t" represents time after launch in seconds). How many seconds after launch
will it take for her snowballs to land back on the ground?

6 (3) - 4 + 32

hope this

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)
