Answer:
where is your questions figure
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.
We know that we're starting from a certain number m and, after subtracting 23, we're left with -50.
So, you can invent any word problem involving some initial amount, a subtraction of 23, and a result of -50. For example:
"Mary spent $23, and her bank account reads $-50. How much money did Mary have in the first place?".
or
"After the temperature dropped 23 degrees, it was -50 degrees outside. What was the temperature before the drop?"
I'm assuming you're looking for the measure of angle y. Rule is that angle y will be equal to 1/2 of its intercepted arc. That arc measures 360-160-60 which is 140. Half of 140 is 70. So the first choice above is the one you want.
