Question

(1,-3) is not a solution to the inequality y > 4x-3 is this true of false

Answer 1

$y>4x-3$

To prove if (1, -3) is a solution for the inequality substitute in the inequality the x by 1 and the y by -3:

$\begin{gathered} -3>4(1)-3 \\ -3>4-3 \\ -3>1 \end{gathered}$

As -3 is not greather than 1, (1, -3) is not a solution for the inequality.

Then, the given statement is true
