In a standared coordinate system, the graph of the equation y=-3x+6 is
A. not a line
B. a vertical line.
C. a horizontal line.
D. a line rising to the right.
E. a line falling to the right.
-------------------
The eqn is in the standard "slope-intercept" form, y = mx + b
m is the slope, and here it's -3.
A negative slope is "downhill" from left to right, so it's E.
