Answer:
24
Step-by-step explanation:
In this question, you have to solve by plugging in the value to the "k" variable and solve.
Solve:
5(3)^2 - 7(3)
3^2 = 9
5(9) - 7(3)
45 - 7(3)
45 - 21 = 24
Your final answer would be 24.
5(9) - 21
45 - 21

all in all it's y=x
A (4,1); B (0,-2)
G=delta y
--------
delta x
1-(-2)
-------
4-0
3/4=G
3/4=y-1/x-4
4 (y-1)=3 (x-4)
4y-4=3x-12
4y=3x+4-12
y=3/4x-3
