Answer:
The distance is √ 85 units
Step-by-step explanation:
To find the exact value, all we will simply do is to use the distance formula to solve;
D =√ (x₂ - x₁)²  +  (y₂ - y₁)²
From the question given;
The points given are  (−1, 4)  and (6, −2)
so;   x₁  = -1         y₁ = 4      x₂ = 6      y₂ = -2
We can now proceed to substitute the formula into the equation
D = √ (x₂ - x₁)²  +  (y₂ - y₁)²
    =√ (6 - -1)²  +  (-2 - 4)²
    =√ (6+ 1)²  +  (-2 - 4)²
    =√ (7)²  +  (-6)²
    =√ 49  +  36
    =√ 85
     The distance is √ 85 units
