Answer:
A segment
Step-by-step explanation:
A line is a straight path that is infinitely long.
A line segment is a section of a line. It consists of two points, which mark the beginning and the end of the segment, and all points in between.
In the diagram, the segment consists of the points A and B and all the points between them.
The line itself extends infinitely both left and right.
Answer:
y = x + 7
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = , hence
y = x + c ← is the partial equation
to find c substitute (4, 9) into the partial equation
9 = 2 + c ⇒ c = 9 - 2 = 7
y = x + 7 ← equation in slope-intercept form
