Question

Draw the graphs in he Cartesian plane of each of the following linear equations.

(iv) y + 4 = 2y + 7

Answer 1

$$\begin{gathered} y+4=2y+7 \\ \Rightarrow -y=3 \\ \Rightarrow y=-3 \end{gathered}$$

This equation is of the form y = a.
Hence, graph of this equation is a line parallel to X-axis at a distance of 3 units in the negative direction of Y-axis.
