Which answer shows y+2x&lt;4x-3,rewritten to isolate y and its graph?
ra1l [238]

The inequality is y < 2x - 3 and the graph of the inequality is graph (a)

<h3>How to isolate y?</h3>

The inequality is given as:

y + 2x < 4x - 3

Subtract 2x from both sides of the inequality

y < 2x - 3

The above inequality uses the < symbol.

This means that the line of the inequality is a dotted line, it is shaded to the right and it crosses the y-axis at y = -3

Hence, the graph of the inequality is graph (a)
