## Intermediate Algebra: Connecting Concepts through Application

a) $= \frac{2}{3}$ b) $y = 4$ c) $x = -6$ d) $y = \frac{2}{3}x + 4$
a) Slope at point $(24, 20)$ and $(-6, 0)$ $m = \frac{20-0}{24-(-6)}$ $= \frac{20}{24+6}$ $= \frac{20}{30}$ $= \frac{2}{3}$ b) $y$ intercept: Where $x = 0$, what is the $y$ value / $y$ intercept $y = 4$ at point $(0, 4)$ c) $x$ intercept: Where $y = 0$, what is the $x$ value / $x$ intercept $x = -6$ at point $(-6, 0)$ d) Equation $y = mx + b$ $y = \frac{2}{3}x + 4$
