Question

MATH PLEASE HELP!!!!!!!!!!!

Answer 1

O to A = (-8,2)(0,0) = (0 - (-8) / (0 - 2) = -8/2 = -4
A to B = (-12,3)(-8,2) = (2 - 3) / (-8 - (-12) = -1/4
so O to A is 4 times the slope of A to B
=====================
initial value is the y int....5
====================
(0,200)(1,160)
slope = (160 - 200) / (1 - 0) = - 40

u have a y int of 200
ur equation is : y = -40x + 200
==================
(0,25)(1,40)
slope = (40 - 25) / (1 - 0) = 15

y = mx + b
slope(m) = 15
(0,25)...x = 0 and y = 25
sub and find b
25 = 15(0) + b
25 = b <=== this is ur fixed amount
