I think this is asking what power when the first number given is raised to it will equal the number within the parentheses. So, for example, the answer to the first question would be 5 because 2^5 = 32. 10^3 = 1000, so the answer is 3, and so on.
The angle is in the third quadrant.
It would be a ray, because it’s continually moving in one direction.
A line is doesn’t have any endpoint and it goes forever in both directions.
A point is just a dot.
A line segment has two endpoints and it doesn’t go forever in either direction.
A plane is a flat surface that goes continually in both directions.
And a ray has one endpoint and continues in one direction, like your laser pointer.
Let x be the number of circuit boards that can be produced and m be the number of capacitors per circuit board
y = mx
140 capacitors allowed the production of 35 boards.
140 = 35x
x = 4
No circuit boards can be made without capacitors so the line's y intercept is 0. No capacitors are used if no circuit boards are to be made so the x intercept is also 0.
