Things to know to solve this problem:
➡ Slope = [tex]\frac{rise}{run} or\frac{change.in.y}{change.in.x}[/tex]
➡ If the line is going up it'll be positive
➡ If the line is going down it'll be negative
Left One:
➡ [tex]\frac{rise}{run}=\frac{1}{2}[/tex]
➡ Going up is +
Answer = [tex]\frac{1}{2}[/tex]
Right One:
➡ [tex]\frac{rise}{run}=\frac{1}{2}[/tex]
➡ Going down is -
Answer = [tex]-\frac{1}{2}[/tex]
Hope this helps have a nice day :D
