Find the

Find the image A´ of point A [1,2] in axial symmetry with the axis p: x = -1 + 3t, y = -2 + t (t = are real number)

Correct answer:

x =  3
y =  -3

Step-by-step explanation:

x0=1 y0=2 n=(3,1)  n:3x+1y+c=0  3 1+1 2+c=0  c=5  n:3x+y5=0  3 (1+3 t)+(2+t)5=0  10t=10  t=1  x1=1+3 t=1+3 1=2 y1=2+t=2+1=1 x=x1+x0=2+1=3
y=y1y0=(1)2=3

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.
Do you have a linear equation or system of equations and looking for its solution? Or do you have a quadratic equation?
Pythagorean theorem is the base for the right triangle calculator.
