Answer
See below:
Work Step by Step
a) The slope of the line is the gradient and shows change as opposed to 2 different variables.
$m= \frac{\triangle y}{\triangle x}= \frac{-2-4}{1+1}=-3$
b) We simply put it in slope-intercept form.
$3y=-6x+12$
$y=-2x+4$
Slope is -2, y-int is 4
C) Use point slope:
$y-2=3(x-1)$
c)
