Explanation

Step 1

When a line slopes up from left to right, it has a positive slope(red line)

When a line slopes down from left to right, it has a negative slope(purple line)

When there is no change in y as x changes, the graph of the line is horizontal. A horizontal line has a slope of zero.(blue line)

When the line is a vertical line, the slope is undefined(green line)

Step 2

identify every slope in the picture following step 1

line1:line slopes down from left to right,then it is a negative slope

line2:the line slopes up from left to right,then it is a positive slope

line3:the line is a vertical line,then it is a undefinded slope

line4:the lines is horizontal, then the slope is zero

I hope this helps you
