The line Y = 1 is a horizontal line; its slope is zero.
A line perpendicular to Y = 1 is a vertical line.
Its slope is undefined.
(This does NOT mean that it's infinite, or anything else.
The slope of a vertical line is undefined. It doesn't have
a name or a symbol. It's nothing.)
It’s a right angle! which equals to 90° you already have 20° and 8° so you add them together and you get 28. now you have to subtract 90-28 which equals to 62.
ANSWER: 62°
Answer:
x=y-4
Step-by-step explanation:
y=x+4
-4
y-4=x
A graph can show that a rate of change is constant as long as the graph is of a straight line.
Any curvature in the line suggests a rate of change that is variable, but otherwise it is constant.
