So if the "i" becomes confusing, just think of it as x
so it would become (-12+48x) +(15+21x)
then you would split up the terms by constants and coefficients
-12+15 +48x+21x
3+69x and then you substitute back for i
3+69i
Y = 5x + b
Plug in the point
35 = 5(-8) + b
35 = -40 + b, b = 75
Solution: y = 5x + 75
Coordinates after 270 clockwise rotation is (-6,-2), (-3,-5) and (-8, -5).
<h3>What is graph?</h3>
Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given coordinates are: (-2,6) , (-5, 3) and (-5, 8)
For 270° clockwise about the origin, we have the following rule:
(x, y)= (-y, x)
So,
coordinates (-2,6) change into (-6,-2)
coordinates (-5, 3) change into (-3,-5)
coordinates (-5, 8) change into (-8, -5).

Answer:
The measure of angle 4 is 48 degrees.
Step-by-step explanation:
When two angles <u>forming an X</u>
- shape share a common vertex and
- oppose each other
the angle has the same value.
We call this type of angles opposing angles or vertical angles.
