Aline passes through (2, 9) and has a zero slope. write an equation of the line satisfying the given conditions.
a. x = 2 b. x = 9 c. y = 9 d. y = 2

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

$630

1. you add 240 and 350
240 + 350 = 590
2. subtract 720 from 590
720 - 590 = 130
3. add 500 and 130
500 + 130 = 630
