## Intermediate Algebra: Connecting Concepts through Application

a) $= -\frac{5}{2}$ b)$x = 2$ c) $y = 5$ d) $y = -\frac{5}{2}x + 5$
a) Slope: Take any two points and find the slope, points $(-2,10)$ and $(6, -10)$ $m = \frac{-10-10}{6-(-2)}$ $= \frac{-20}{6+2}$ $= \frac{-20}{8}$ $= -\frac{5}{2}$ b) $x$ intercept, when the $y$ coordinate is $= 0$ $x = 2$ at the point $(2, 0)$ c) $y$ intercept, when the $x$ coordinate is $= 0$ $y = 5$ at the point $(0,5)$ d) Equation of line $y = mx + b$ $y = -\frac{5}{2}x + 5$
