pter#1 Exhibit 1A-4 Straight line 80 60 Y value A B c D 40 20 0 20 40 60 80 X value Straight line A-D in Exhibit 1A-4 shows that: a. as the Y value increases by 40, the X value increases by 80 so the slope is 1/2. O b. as the X value increases by 80, the Y value increases by 40 so the slope is 2. O c. increasing values for Y do not affect the value of X. O d. increasing values for X do not affect the value of Y. O- Icon Key
