How many points does a line have?
a line has to have at least 2 points.a plane has to have at least 3 points.______________It takes two points to define a unique line in Euclidean space. But every line and every line segment contains infinitely many points. The same is true for planes in Euclidean space. You need at least 3 points to define a unique plane, but every plane containes infinitely many points and infinitely many lines or line segments.
Why do you line up the decimal points when adding and subtracting?
you have to line up the decimal points because you need to keep each place value in the same column so when you add or subtract you wont make any errors
How do you graph a parallel line?
You need to know what the graph points are.
How many points are needed to determine a trajectory line?
To determine a trajectory line, only two points are needed. These two points can be used to calculate the slope, which represents the direction and angle of the trajectory. Additional points can be used to further refine the trajectory line and estimate its accuracy.
Why do you need to find the equation of a line?
So that you can plot out the points of a straight line on graph paper.
