The line passes through the point (2,-9) and has a zero slope. Write the answer in slope-intercept form.

Okay so for finding the equation of a line, which is a function, the equation is set to y, so you can eliminate A and B. When the slope of an equation is 0, we are saying that the y value of any point of the line is going to be the same, which is 9 from the given point (2,9).

So the answer is C. y=9

Step-by-step explanation:

In order to calculate for the number of cacti in the garden, we simply multiply the total number of plants with the decimal equivalent of the cacti in the circle graph. That is,
                            number of cacti = (500 trees) x 0.25 = 125
 
Thus, the answer to this item is 125.
