Answer:
B. f-1(x) = (5/2) x - 6.
Step-by-step explanation:
f(x) = (2x + 12) / 5
5 f(x) = 2x + 12
2x = 5 f(x) - 12
x = (5 f(x) - 12) / 2 ow replace the x by f-1(x) and f(x) by x:
f-1(x) = ( 5x - 12)/ 2
f-1(x) = (5/2) x - 6.
Answer:
-1
Step-by-step explanation:
Remember, slope is rise/run
Start from a point on the line and count up and over until you reach another point on the line.
For example, start from (0,-2), count up and left until you get to (-2,0). This gets you 2/2, which reduces to 1.
Since the line represents a negative slope, the slope is -1.
