Step-by-step explanation:
I hope this helps you
The first one would be approximately -0.8. It has a negative slope and the data points are fairly close together.
The second one is almost a straight line so it would be very close to 1. I would say 0.97
The closer the data is to a straight line the closer the r value is to 1 or negative 1.
Hope this helps.
100 degrees - all angle measurements in a triangle will add up to 180 degrees (45+55 = 100, 180-100 = 80)
B + 1.1 = -11
Subtract 1.1 from both sides to get b.
So, b = -12.1
Rearranging the first equation gives:
Substituting this into the other equation gives:
If x=-1:
So
x=-1, y=-5
