Answer:
4.31
Step-by-step explanation:
The distance from point (x, y) to line ax +by +c = 0 is given by the formula ...
d = |ax +by +c|/√(a² +b²)
Putting the equation of the line into the required form, we have ...
5x +y +3 = 0
So, the distance from point (4, -1) to the line is ...
d = |5(4) +(-1) +3|/√(5² +1²) = 22/√26
d ≈ 4.31
