Answer:
Step-by-step explanation:
If A = (-3,-1) and B = (4,4), the slope of AB is
Two perpendicular lines have slopes that have product of -1:
The equation of the line BC with slope -1.4 and passing through the point B(4,4) is
you can measure the first angle with a protractor and then measure the other one see if there is a different angle
In order for two linear lines to be perpendicular, the product of their gradient must be -1.
Let's take y = x + b and y = -x + b
This is already in the form: y = mx + b, where m is 1 and -1 respectively.
Since the product of their gradient is -1, they are said to be perpendicular.
Answer: It is answer C.
Step-by-step explanation: Because of the location and angle of the line, it intersects at 9 on the y axis and 1 on the x, therefore giving you 9 over 1
