Answer:
Perpendicular lines have slope that are negative reciprocals.
The slope of the perpendicular line is M = -1/3.
Step-by-step explanation:
(4,-1) --> X = 4, Y = -1, M = -1/3
y = Mx + b
-1 = (-1/3)*4 + b
-1 = (-4/3) + b
-3/3 = (-4/3) + b
-3 = -4 + 3b
1 = 3b
b = 1/3
y = (-1/3)X + 1/3
Answer:
2c^2 + 4
Step-by-step explanation:
2c^2 + 4 + 9 - 9 <- simplify
4 + 9 = 13, 13 - 9 = 4
2c^2 + 4
Hope this helps :)
(The ^ shows that it's an exponent)
First let's find the factors of each number:
19: 1,19
21: 1,3,7,21
23: 1,23
25: 1,5,25
21 has 4 factors, 25 has 3 and 23 and 19 are both prime numbers (with two factors). 21 has the most factors.
Answer:
Positive, linear equation.
Step-by-step explanation:
Even though the graphs coordinates looks a little dicey, all of the points are still going upward which is a positive linear equation.
