Linear equations are written as y = C1x + C2 where C1 & C2 are
constants. They are graphed by plugging in numbers for y or x and solve
for the other. For example if you have an equation y = 3x + 6 you then
for y = 1 you have 1 = 3x + 6 -> x = -5/3 you then take the two
coordinates (-5/3,1) and plot the point do this for further numbers and
connect the points with a straight line. Shifting the graph up or down
will change the value of C2 and shifting the graph left or right will
change C1.
The coefficient of determination is the square of the correlation coefficient, and the value is 0.0151
<h3>How to determine the coefficient of determination?</h3>
The given parameter is:
Correlation coefficient, r = 0.123
Rewrite as:
r = 0.123
Take the square of both sides
r² = 0.123²
Evaluate the square
r² = 0.015129
Approximate
r² = 0.0151
The coefficient of determination is represented by r²
Hence, the coefficient of determination is 0.0151
