Answer:
gradient = - 
Step-by-step explanation:
Calculate the gradient m using the gradient formula
m = 
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (3, 1) ← 2 points on the line
m = 
= 
= -
9/2, 18/4, 27/6 you just make a equivalent fraction then multiply the whole number by the denominator and add the numerator
