This transformation is called a rotation.
To get the slope, we will need two points that belong to the line.
From the graph, we can get two points as follows:
(0,-1) and (-1,1)
The slope of the curve can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)
Substitute with the two points to get the slope as follows:
slope = (1--1) / (-1-0) = (2) / (-1) = -2
Yes. Any number that is a multiple of 2 is even & the last digit of everyone of those numbers is an even number.
