You need to multiply 19.797 by 10 two times to reach 1979.7
Plotting the points could help you notice that they lie along a parabola. In particular, you can see that 
is always 4 more than 
.
So, the relation is
In the proof given, BC║AD and CD║BA because: B. slopes of opposite sides are equal.
<h3>What is the Slope of Parallel Lines?</h3>
If two lines are parallel, they will have the same slope value,.
Slope = rise/run.
Slope of BC = rise/run = -2/5
Slope of AD = -2/5
Slope of BA = rise/run = -6/1 = -6
Slope of BA = rise/run = -6/1 = -6
Therefore, we can conclude that BC║AD and CD║BA because: B. slopes of opposite sides are equal.
