y = − 3 Explanation: Begin by finding the slope of the line using the formula m = y 2 − y 1 x 2 − x 1 For the points ( 2 , − 3 ) and ( 1 , − 3 ) x 1 = 2
x 2 = − 3
x 2 = 1
y 2 = − 3 m = − 3 − ( − 3 ) 1 − 2 m = 0 − 1 m = 0 This equation is actually a horizontal line running through the y axis at y = − 3
