Question

Here's a graph of a linear function. write the equation that describes that function.

Answer 1

Answer:

y = 1/4x + 5

Step-by-step explanation:

Here, we want to write the equation of the function

Generally we can have the equation of a straight line as;

y = mx + b

m is slope, b is the y-intercept

From the graph we have the y-intercept as 5

To get the slope, we select any two points and apply the slope formula

Let us have the points;

(8,7) and (4,6)

the slope will be;

m = (y2-y1)/(x2-x1) = (6-7)/(4-8) = 1/4

So the equation of the line is;

y = 1/4x + 5
