Answer:

One point

Step-by-step explanation:

Given information: line d intersects plane f.

Plane: In mathematics, a flat, 2D surface that extends infinitely far is know as plane.

Line: A line of infinite number of points that extends infinitely in two directions is know as line.

In 3D, a line can be parallel to the plane, lie on the plane and intersect then plane.

(a) If line is parallel, then no point on the line lie on the plane.

(b) If line is on the plane, then infinite points on the line also lie on the plane.

It is given that line d intersects plane f.

If line d intersects plane f, then only 1 one point on line d also lie on plane f.

PLEASE HELP!!!!

You should put 4 as x, -3 as y and a as slope to make an equation :
$- 3 = a \times 4$
then you can find the slope and the correct equation of the line :

the slope is :
$- 3 = 4a \\ a = \frac{ - 3}{4}$
so the equation of the line will be
$y = \frac{ - 3}{4} x$
D is true
hope this helps

D. A rectangle and an isosceles triangle

Step-by-step explanation:

In the figure attached, the sign is shown. There we can see an arrow, which can be decomposed into a rectangle (on the left of the figure) and an isosceles triangle (on the right of the figure)
