Slope is the change in Y over the change in X:
Slope = (6 - -8) / (5 - -3)
Slope = (6+8) / (5+3)
Slope = 14/8
Slope = 7/4
1000ft > 300 yd
1ft=3yd
1000ft=333.33yd
the correct answer is a, because a vertical angle is made of 2 intercepting lines.
What is the question? And there is no image of the scale.
