Chapter 3 - Section 3.1 - Graphing Equations - Exercise Set: 20


Neither are solutions

Work Step by Step

We are given that $5x-3y=9$. In order to see whether each ordered pair is a solution of the given equation, we can plug in the ordered pair to the equation. For (0,3): $5\times0-3\times3=-9\ne9$ So, (0,3) is not a solution. For ($\frac{12}{5}$,-1): $5\times\frac{12}{5}-3\times-1=12+3=15\ne9$ So, ($\frac{12}{5}$,-1) is not a solution.
