What is the an equation of the horizontal line through (5,-2)
Vikki [24]

Answer: y = -2

Step-by-step explanation: Because the line is horizontal, the slope is 0. So on a graph the line will cut through (5,-2), (4,-2), (3,-2), (2,-2), (1,-2), and (0,-2). The line can pass through any x value, but the y value will always stay the same for this line. This means the y-intercept is -2. Because the slope is 0 and the y-intercept is -2, the equation is y = 0x -2, but there is no value in keeping the 0. So, you take it out leaving you with y = -2.

Hope This Helps! Good Luck and Have a Great Night!
