Answer:
slope = -1.5
Step-by-step explanation:
A set of three or more points are said to be collinear if they all lie on the same straight line.
We have been given the following collinear set of points;
P(0, 3), Q(2, 0), R(4, -3)
This implies that P, Q, and R lie on the same line.
The slope of a line is defined as; (change in y)/(change in x)
Using the points P and Q, the slope of the line is calculated as;
(0-3)/(2-0) = -3/2 = -1.5
Answer:
-3/2
Step-by-step explanation:
The width of backyard is 45 feet.
Step-by-step explanation:
Given,
Length of backyard = 120 feet
Perimeter of backyard = 330 feet
Width of backyard = w
Perimeter = 2(Length + Width)
Dividing both sides by 2
The width of backyard is 45 feet.
