Direction vector

The line p is given by the point P [- 0,5; 1] and the direction vector s = (1,5; - 3) determines:
A) value of parameter t for points X [- 1,5; 3], Y [1; - 2] lines p
B) whether the points R [0,5; - 1], S [1,5; 3] lies on the line p
C) parametric equations of the line m || p if the line m passes through the origin of the coordinate system
D) parametric equations of the line n _ | _ p, if the line n passes through the point N [- 2; 4]

Result

t1 =  -0.6667
t2 =  1
R=

t2 =S=

t2 =mx = 1.5t
my = -3t
nx = -2+3t
ny = 4-1.5t

Tips for related online calculators
The line slope calculator is helpful for basic calculations in analytic geometry. The coordinates of two points in the plane calculate slope, normal and parametric line equation(s), slope, directional angle, direction vector, the length of the segment, intersections of the coordinate axes, etc.
Our vector sum calculator can add two vectors given by their magnitudes and by included angle.
