slope = rise over run = y/x
A (-1,3) slope = 3/-1 = -3
B (1,2) slope = 2/1 = 2
C (-3,-1) slope = -1/-3 = 1/3
2 lines need to be negative reciprocals in order to be a right triangle
negative reciprocal of -3 is 1/3
so this is a right triangle
Are a and b two points on a line
If they are you can use the distance formula
First let's rewrite it...
18a^2 + 20a + 8
Factor out a 2
2 (9a^2 + 10a + 4)
Answer:
(0,22) (22,)
Step-by-step explanation:
These are the points where the line crosses the X and Y axis. Hope this is what you're looking for
