Answer:So slope 1 would be positiveSlope 2 would be negative Slope 3 would be zero Step-by-step explanation:If the slope is moving up from left to right, then it is positiveIf the slope is moving down from left to right, then it is negativeIf the slope is a vertical line and is not moving left/right, then it is undefinedIf the slope is a horizontal line and is not moving up/down, then it is zeroSo slope 1 would be positive because it is moving up from left to right.Slope 2 would be negative because it is moving down from left to right. Slope 3 would be zero because it is a horizontal line that is not moving up or down.Hope this helped!
