Solution
Classify the following systems of equations as consistent, inconsistent, or dependent WITHOUT
using any of the previous methods. (graphing, elimination, substitution) (4x + 3y = 7 ) (2x – y
= 10) -------------------- Rewrite in slope-intercept form: y = (-4/3)x + (7/3) y = 2x - 10 -------------
------- The slopes are different so the lines intersect at one point. Therefore the system is
consistent.
