Let the point P have coordinates (p, q, r) and let the equation of the plane be ax + by +cz + d = 0Then the distance from the point to the plane is
abs(ap + bq + cr) / sqrt(a^2 + b^2 + c^2).
To find the x-coordinate of a point on the xy-plane, you look at the horizontal distance of the point from the y-axis. The y-coordinate of a point on the xy-plane is the vertical distance of the point from the x-axis.
yes
True
graph it
Point 1 = (x1, y1)Point2 = (x2, y2)d = ((x2 -x1)2 + ( y2 -x2 )2 )0.5

True
yes
another point
Unless the line is a subset of the plane, the intersection is a point.
True
True
well, you find the two cooridinates on the plane and then graph them! KINDA EASY!
You use the distance formula.
graph it
The answer is the x coordinate of the point.
Point 1 = (x1, y1)Point2 = (x2, y2)d = ((x2 -x1)2 + ( y2 -x2 )2 )0.5
