10) You have the following equations of two lines, with definite intervals:
y = (4/5)x - 1.5 from x = 2 to x = 6
y = (4/5)x + 3 from x = 0 to x = 3
In order to grah the given lines, you first calculate the values of the functions for the limits of the intervals, just as follow:
from x = 2 to x = 6
y = (4/5)(2) - 1.5 = 0.1
y = (4/5)(6) - 1.5 = 3.3
from x = 0 to x = 3
y = (4/5)(0) + 3 = 3
y = (4/5)(3) + 3 = 5.4
Next, you graph the two lines by taking into account the limits, and you connect the endpoints of the segment, just as follow:
where the blue lines are the the given functions, and the orange lines are the connection between the endpoints of the functions.
