Exercises: Finding line equations

1. insert $m$ and the coordinates of the point $P$ into the general line equation and solve for $t$.

2. Plug $m$ and $t$ into the general linear equation $\Rightarrow y=-2x-3$

Drawing the line

Draw the given point $P(-3\text{∣}3)$ in the coordinate system. Then draw a slope triangle by moving 1 unit to the right and 2 units down ($m=-2$). Mark the point $Q$ there. Connect $P$ and $Q$ to form a line.
