Answer:
The perpendicular gradient is 2x
We must remember that average is simply the sum of all the
scores divided by the number of scores. So:
165 = (157 + 161 + X) / 3
Calculating for the score of the third bowler X:
318 + X = 495
X = 177
Therefore the score of the third bowler must be 177 or
greater. Hence:
<span>X ≥ 177</span>
Slope = (-2 + 4)/(-2-2) = 2/-4 = -1/2
y = mx + b
so
b = y - mx
b = -2 -(-1/2)(-2)
b = -2 - 1
b = - 3
equation
y = -1/2x - 3
answer is B.
y = -1/2x - 3
