The linear equation that passes through the two given points is:

7 = (-3/2)*x + 31/2.

What is the equation of the line?

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

slope = (y2 - y1)/(x2 - x1)

Here the line passes through (5, 8) and (9, 2), then the slope is:

m = (2 - 8)/(9 - 5) = -6/4 = -3/2

So we have:

y = (-3/2)*x + b

To find the value of b, we can replace the values of one of the points in the equation, I will use (5, 8)

8 = (-3/2)*5 + b

8 = -15/2 + b

8 + 15/2 = b

31/2 = b

The line is: y = (-3/2)*x + 31/2
