Answer:
5 units.
Step-by-step explanation:
In order to find the distance between the line y = -2x + 1 and the point (-4, 4), we need to find the position of the line at x = -4. Shortest distance between two objects is a straight line, right?
So y = -2(-4) + 1 = 9; (-4, 9).
Finding the distance between (-4, 4) and (-4, 9) gives us the answer of 5.
Answer:
2.2 units
Step-by-step explanation:
Equation of the Perpendicular from (-4,4) to the given line:
m1 × m2 = -1
y = (½)x + c
4 = (½)(-4) + c
c = 6
y = (½)x + 6
Foot of the Perpendicular
(½)x + 6 = -2x + 1
5/2 x = -5
x = -2
y = -2(-2) + 1 = 5
(-2,5) and (-4,4)
sqrt[(5-4)² + (-2+4)²]
sqrt(1 + 4)
sqrt(5)
