Answer
a) $= -\frac{5}{2}$
b)$x = 2$
c) $y = 5$
d) $y = -\frac{5}{2}x + 5$
Work Step by Step
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
$y = mx + b$
$y = -\frac{5}{2}x + 5$
