Answer: Choice A
Reason:
Each linear equation is of the form y = mx+b
where
For example, the equation y = -3x+5 has m = -3 as the slope and b = 5 as the y intercept.
The y intercept tells us where this line crosses the y axis. The slope helps us determine another point on the line. We start at (0,5) and move down 3, then to the right 1 to arrive at (1,2) as another point on this line.
Side note: Think of y = x+2 as y = 1x+2
