Test it by the vertical line test. That is, if a vertical line passes through the two points of the graph, this graph is not the graph of a function.
All of them...?
False
The line is vertical on the graph. Its slope is infinite.
goes through the origin, up and to the right
When points are marked on a graph, a line is often drawn across the dots plotted. A line of best fit is a straight line that goes through as many of such points as possible.
For any line, there needs to be two points. If the line passes through points and extends in both directions forever, it's a line. If the line just goes between the two points, its called a line segment. If the line goes through both points but only extends in one direction, it's a ray.
It is a straight line which goes through the points (2,0) and (0, -4)
A line of best fit
Test it by the vertical line test. That is, if a vertical line passes through the two points of the graph, this graph is not the graph of a function.
A line plot is just a graph with points and a line graph the points are connected.
For example, if the slope at a certain point is 1.5, you can draw a line that goes through the specified point, with that slope. The line would represent the slope at that point. If you want to graph the slope at ALL POINTS, take the derivative of the function, and graph the derivative. The derivative shows the slope of a function at all points.
No, the best fit line need not go through any data point on a graph.
The line goes through the midpoint, which is halfway between points. The distances are equal to each other, and proves that they are equidistant.
False
It makes a line ,it goes through the origin, it has a constant
No. Because a vertical line will pass through two points on the graph.
