Answer:
The equation of the line is

Explanation:
Equation of a line:
The equation of a line has the following format:

In which m is the slope and b is the y-intercept.
Slope:
Having two points, the slope is given by the change in y divided by the change in x. Points (2,4) and (7,2), so:
Change in y: 2 - 4 = -2
Change in x: 7 - 2 = 5
Slope:

So

(2,4)
This means that when
. So



The equation of the line is
