Describe what the graph of each linear equation will look like in the coordinate plane. (Hint: Rewrite the equation if necessary so that it is in a more recognizable form.) $$ 5 y=-15 $$

For each pair of equations, give the slopes of the lines and then determine whether the two lines are parallel, perpendicular, or neither. See Example \(6 .\) $$ \begin{aligned} &5 x-3 y=-2\\\ &3 x-5 y=-8 \end{aligned} $$

Write an equation for each line passing through the given point and having the given slope. Give the final answer in slope-intercept form. See Examples 5 and \(6 .\) $$ (4,2), m=-\frac{1}{3} $$

Write an equation for each line passing through the given point and having the given slope. Give the final answer in slope-intercept form. See Examples 5 and \(6 .\) $$ (6,-3), m=-\frac{4}{5} $$

For each pair of equations, give the slopes of the lines and then determine whether the two lines are parallel, perpendicular, or neither. See Example \(6 .\) $$ \begin{aligned} &3 x-2 y=6\\\ &2 x+3 y=3 \end{aligned} $$

Fill in each blank with the word positive or the word negative. The point with coordinates is in quadrant IV if \(x\) is ______ and \(y\) is _______
