Currently pursuing an actuarial science/mathematics major at the University of Texas at Austin. Set to graduate in May 2020.
$61-72$ Quadratic Equations Find all solutions of the equationand express them in the form $a+b i .$$$x^{2}+3 x+7=0$$
In Exercises 1 and 2, estimate the slope of the line.GRAPH
In Exercises 3–6, find the slope of the line through the pair of points.$$(-2,1) \text { and }(5,-3)$$
In Exercises 3–6, find the slope of the line through the pair of points.$$(5,-3) \text { and }(-4,12)$$
In Exercises 7–10, find the value of $x$ or $y$ so that the line through the pair of points has the given slope.$$\begin{array}{ll}{\text { Points }} & {\text { Slope }} \\ {(-2,3) \text { and }(4, y)} & {m=-3}\end{array}$$
In Exercises 7–10, find the value of $x$ or $y$ so that the line through the pair of points has the given slope.$$\begin{array}{ll}{\text { Points }} & {\text { Slope }} \\ {(-8,-2) \text { and }(x, 2)} & {m=1/2}\end{array}$$
