Answer:
The new graph same y-intercept but a slope of -200 instead of -300 as in the old graph.
Explanation:
The two equations are written in the form of y = mx + b. m is the slope and b is the y-intercept.
 m, Slope  b, Y-Intercept
Initial Plan:  y = -300x + 2300 -300 2300
Modified Plan: y = -200x + 2300  -200 2300
The new graph same y-intercept but a slope of -200 instead of -300 as in the old graph.
