1. 2(4) - 4y = 20
8 -4y = 20
8-8 -4y = 20 - 8
-4/-4y = 12/-4
y = -3
The slope definitions:
The
slope is the change in y divided by the change in x.
The
slope is the ratio of rise to run.
The
slope is the rate of change of the function at a certain point.
The
slope is the first derivative of a function.
The
slope is the tangent of the slant/inclined angle
So we are interested in this one: "The
slope is the ratio of rise to run"
