find k so that the line through(-3,4) and (k,8) is
A) parallel to 5x-4x=3
--------
X = -3
It's a line parallel to the y-axis, thru the point (-3,0)
k = -3
================
B)5y-4x=3
Find the slope, m
Solve for y
y = (4/5)x + 3/5
m = 4/5
---
m = diffy/diffx
m = (4-8)/(-3-k) = 4/5
4/(k+3) = 4/5
4*(k+3) = 20
k = 2
