Find equation of the line shown

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept

From the graph we have the y-intercept (0, 9) → b = 9.

Substitute it to the equation of a line:

From the graph we have the x-intercept (9, 0) → x = 9, y = 0.

Substitute to the equation:

         subtract 9 from both sides

        divide both sides by 9

Finally:

answer: 12
