The graph of y = mx is given in the figure to the right. Sketch the graphs for each of the
following on the same figure. Explain your answers. Complete parts (a) through (d) below.
b. y=mx-1; Explain this line in comparison to the original line.
The line is
to y = mx and passes through the point (D,
c. y=2mx; Explain this line compared to the original line..
The slope is
times the original slope, and the line passes through the point (0,
d. y=2mx; Explain this line compared to the original line.
The slope is times the original slope, and the line passes through the point (D,
Sketch the graphs for (a) y = mx +1, (b) y = mx-1, (c) y = 2mx, and (d) y = 2mx on
the same figure and label each line using the letter of its part. Use the graphing tool to
