Answer:
y = 2x - 4 is in y = mx + b form, where m is the slope and b is the y-intercept
using this knowledge, we can graph the line
our y-intercept as an ordered pair would be (0,-4), and our slope is 2, also known as 2/1
we start by graphing the point (0,-4) and graph the next point using the slope
the slope is rise/run, also known as y/x
we would go up 2 points from (0,-4) which would bring us to (0,-2), then we would move 1 point to the right, and we would be at (1,-2)
with the points (0,-4) and (1,-2) we can graph the line connecting those 2 points
