Answer:
The first graph shows a slope of 3.
Step-by-step explanation:
If the slope is 3, it's actually 3/1 because of rise/run. So you find any point on the graph that's directly between two lines, like (-1,-5). Since the line is positive, you would go right one and up three. Then you see if that point is directly between two lines. The next point is (0, -2). If you did the same on the second graph, it wouldn't match up.

is 1 i think
Step-by-step explanation:
Answer:
56.52 inches
Step-by-step explanation:
The circumference of a circle can be found using:

We know the diameter is 18, and
is being rounded to 3.14, so we can substitute them in.
c=3.14*18 <em>Multiply</em>
c=56.52
So, the circumference is 56.52 inches
sin = opposite/hypotenuse
sin 40° = 12/x
Cross multiply.
0.64278760968x = 12
Divide both sides by sin 40°.
x = 18.7 (rounded to nearest tenth).
