Answer

$y=\dfrac{1}{2}x+7$ (see graph)

Work Step by Step

We are given the points: $(-6,4),(4,9)$ Determine the slope of the line: $m=\dfrac{9-4}{4-(-6)}=\dfrac{5}{10}=\dfrac{1}{2}$ Determine the equation for the line using the slope and one of the points: $y-9=\dfrac{1}{2}(x-4)$ $y=\dfrac{1}{2}x-2+9$ $y=\dfrac{1}{2}x+7$ Use the two points to graph the function:
