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

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

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
