Proportional relationship
We know a proportional relationship is when one of the variable is obtained by multiplying the other variable by a constant number.
For example, in an equation it can be represented:
<em>y = 2x</em>
<em />
In a table, we can represent it by
<em />
In a graph,
Answer: all of them
180-140=40
B is 40 degrees. For further explanation on this answer, do a little research on supplementary angles.
Answer:

Step-by-step explanation:
Answer:
The missing y -coordinate is 0.
Step-by-step explanation:
Here we know the slope but must find the y-coefficient of one of the points.
y - 2
The slope is m = 1/2 = rise / run = ----------
3 - 7
y - 2
or 1/2 = ---------- which simplifies to -2 = y - 2, which yields y = 0.
-4
The missing y -coordinate is 0.
