For Problems \(13-22\), find the equation of the line that contains the two given points. Express equations in the form \(A x+B y=C\), where \(A, B\), and \(C\) are integers. \((-8,-7)\) and \((-3,-1)\)

Find the slope of the line determined by each pair of points. $$(-2,12),(-10,2)$$

Find the slope of the line determined by each pair of points. $$(a, b),(c, d)$$

For Problems \(13-22\), find the equation of the line that contains the two given points. Express equations in the form \(A x+B y=C\), where \(A, B\), and \(C\) are integers. \((0,0)\) and \((-3,-5)\)

For Problems 1-36, graph each linear equation. (Objective 2) $$ y=0 $$

Solve each system by using either the substitution or the elimination-by- addition method, whichever seems more appropriate. $$\left(\begin{array}{l}x=5 y+7 \\ 4 x+9 y=28\end{array}\right)$$
