M = -4 -4 / 5- 3 = -8/2 = -4
y = -4x + b
4 = -12 + b
b = 16
y = -4x + 16
First you must set f (x) =15:
15 = 2x - 5
Now you must solve like a normal equation:
15 = 2x - 5 )+5
20 = 2*x ):2
10 = x
ANSWER: The value of x is 10
Answer: It's not a function because the line is curved, and it has an exponent in the equation which makes the line curved instead of straight which will make x repeat.
