Answer:

The rise is 5

The run is 6

The rate is 5/6

Step-by-step explanation:

Rise is the change in y, or how many units up the line goes. On this graph, y goes up 5. The run is the change in x, or how many units right the line goes; on this graph, it goes 6 units right in between the points. The rate, or slope, is rise over run, so the final answer is 5/6.

Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k. (1 point) 92 fix)
rewona [7]

Answer:

3

Step-by-step explanation:

g(x) = f(x) + k, is true for all values of x.

At x = 0, f(x) = 2

At x = 0, g(x) = 5

Therefore, at x = 0

=> g(x) = f(x) + k

=> 5 = 2 + k

=> 3 = k

Since, the given relation is true for all real values of x, k is independent of x. Thus k = 3, for every value of x
