What function is shown in the graph above?
Verizon [17]

By definition of <em>linear</em> functions and the comparison with the attached figure, the function that represents the graph is y = (7/15) · x + 4, - 6 ≤ x ≤ 9.

<h3>What kind of function represents the graph?</h3>

Graphically speaking, <em>linear</em> functions represent lines and we see that the line seen in the figure presents two bounds, the points (- 6, 0) and (9, 7). <em>Linear</em> functions are characterized by slope and intercept:

y = m · x + b     (1)

Slope

m = (7 - 0)/[9 - (- 6)]

m = 7/15

Intercept

b = 4

By definition of <em>linear</em> functions and the comparison with the attached figure, the function that represents the graph is y = (7/15) · x + 4, - 6 ≤ x ≤ 9.

Write the equation of a line for a graph hurry!!​
anastassius [24]

Answer:

y = -2x + 2

Step-by-step explanation:

y-intercept is 2 (where the line crosses the y axis)

slope is -2 (fall over run)

written in slope - intercept form, you get y = -2x + 2
