1 answer:
The linear equation of the points is y = 2x + 3
<h3>How to determine the equation?</h3>The points are given as:
(-2, -1), (-1, 1), (0,3), (1,5), (2,7), (3,9)
From the above points, we can see that:
As x increases by 1, the y value increases by 2
This means that the points form a linear equation, and the slope (m) is calculated using:
m = Δy/Δx
This gives
m = 2/1
m = 1
The y-intercept (c) is when x = 0.
From the points, we have:
(x,y) = (0,3)
This means that
c = 3
A linear equation is represented as;
y = mx + c
Substitute the known values
y = 2x + 3
Hence, the linear equation of the points is y = 2x + 3

Answer:
Step-by-step explanation:
The area of the circumference of a circle is:
We know that r is 8, so we can plug that into the formula.
However, there's a problem. We only want 3pi/4 of the circumference, not the entire circle's circumference. Therefore, we have to divide by part/whole. In this case, the part is 3pi/4, and the whole is 2pi (the entire circle is 2pi radians).
