Step-by-step explanation:
Step 1:
To find the slope the formula is given by
Slope = (Δy)/(Δx) =
( Change in Y Co-ordinate)/ (Change in X Co-ordinate) =(y₂-y₁)/(x₂-x₁)
Step 2:
In the given figure y coordinate change from +4 to +1 and X coordinate changes from +1 to +2.
y₂= 4, y₁= 1
x₂= 2 x₁=1
Applying the values in the above formula as follows
Slope= (4-1)/(2-1)
= (3)/(1)
= 3
