I think you forgot part of the question?
The constant is 3.
This is because when x=1, y=3 and when x=2, y=6 so that is a constant change over each interval as seen in the graph which is 3 :)
First, let us solve for the slope of the line which it
intersects with:
m’ = (y2 – y1) / (x2 – x1)
m’ = (-3 – 4) / (-2 – 5)
m’ = 1
The slope of the perpendicular line is the negative
reciprocal, therefore:
m = - 1 / m’
m = - 1 / 1
m = -1
<span>So the slope of the line is -1.</span>
30 degree
The sum of isosceles triangle is 180 degree. And this triangle 2 sides have to be equal.
So one of our angle is 120 degree. Two angle will be 180-120 = 60 degree
Now one angle 60/2=30
