<span>The limitation of
algebra that leads development of calculus is that it can make a complex number
of variables present it as a single variable and then apply the necessary
formula needed to find the answer. After manipulation, the presented single
variable can be changed back to a complex variable by substitution</span>
The slope is rise/run
3 up and 3 to the left: 3/3 = 1
The slope is 1
Assuming graph is 1 units per box and y intercept is (0,y), looking at the graph you can see it’s (0,-1)
The y intercept is (0,-1)
A line is 180°, so the supplementary angel makes up the difference between. 180 - 60 = 120°
