1. A. parallel, because when you get y by itself it is y=-2x+7, the two equations have the same slope which means they are parallel.
2. B. sometimes, in order for two lines to be parallel they have to have the same slope so, it is possible that two lines say with a slope of 3, those would be parallel BUT it doesn't always have to have a positive slope for it to be parallel like in question 1.
3. C. never, If they have the same slope they are parallel despite whatever the y-intercept is.
Answer:
-2
Step-by-step explanation:
Two points (1,0) (0,2) use slope formula 0-2/1-0

Answer:
...........the answer is 7?!
According to the given diagram, the diameter of the circle is 9 feet.
Remember that the radius is half the diameter, so the radius is 4.5 feet.
<h2>Hence, the answer is 4.5 feet.</h2>
