Answer:
y = -1
Step-by-step explanation:
Notice that the line x = 9 is a vertical line, therefore a line perpendicular to it will be a horizontal line of the form y = constant number.
Since we want it to go through the point (9, -1), then we know that that y value needs to be "-1", and the equation of the line will be given by the expression:
y = -1
10 sqaure units in this triangle
A point is a specific coordinate on a line or plane. (An exact location in space)
A line extends forever in both directions.(Infinitely many points that extend forever in both directions)
A ray starts at one point and continues on forever in one direction
A segment is just part of a line. It has two endpoints
A plane is an infinitely large, flat, two-dimensional surface.(Infinitely many intersecting lines that extend forever in all directions.)
