Exercise 1 Page 268

We will determine the equation that has the given graph.

We can see that the y-intercept of the line is y=-9. Therefore, we can begin by writing an equation in slope-intercept form, y= mx+ b, where m is the slope and b is the y-intercept. y= mx -9 Now we will find the slope by substituting (2,0) in the above equation.

We found that the slope is 92. Now we can complete the equation. y= 9/2x -9 Finally, since the given equation is in standard form, we will rewrite the equation in standard form as well.

Therefore, the equation of the line is given in option D.
