Which of the following equations is of a parabola with a vertex at (1, 2)? 1.)y = (+ 1)2-2
2.) y = (x - 1) 2-2
3.)y=(x + 1)2 + 2
4.)y = (x - 1) 2 + 2

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

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)

answer: the answer is ann
