The best fit line must go through all data points on a graph?
False
What is the slope of the line passing through points 31 AND -53?
84
Describe the process of finding slope from a table of values?
to find the slope of the line passing through the points (x1,y1) and (x2,y2) you must do: (y2-y1) / (x2-x1) for the points (3,5) and (4,6): (6-5) / (4-3). you only need two points.
What two criteria must be true for a graph to be a proportional relationship?
It must be a straight line. It must pass through the origin.
How do you get a perpendicular line?
To make perpendicular lines, draw a horizontal line. Then using a compass or tracing around the edge of a curved object, draw one circle ( or just a semi-circle) so that it crosses the horizontal straight line in at least one point. Now rotate the compass or move the curved object to draw another circle (or semi-circle). This second circle (or semi-circle) must cross through the horizontal straight line as the first one did. It also must cross through the first circle (or semi-circle) at two points- above the horizontal straight line and below the horizontal straight line. Next, draw a straight line from where the two circles (or semi-circles) meet above the horizontal straight line through to where they meet below the horizontal straight line. You now have a line perpendicular to the first line.
The best fit line must go through all data points on a graph?
False
What The best-fit line must go through all data points on a graph.?
No, the best fit line need not go through any data point on a graph.
Is the line through points P0 5 and Q1 8 parallel to the line through points R3 3 and S5 1?
No because for them to be parallel with each other they must have the same slopes and their slopes are 3 and -1 respectively
What is a point that does not lie on the same line?
Since it is possible to draw a line through any two points, if there is a point that does not lie on the same line, it must be a third point.
What are the three points for coplanar but not collinear?
Two points (which must lie on a line) and the third point NOT on that line.
How do you find the equation of a tangent line?
In order to find the equation of a tangent line you must take the derivative of the original equation and then find the points that it passes through.
What is the slope of the line passing through points 31 AND -53?
84
When two points on a line are used to name the line the points must always be given alphabetical order?
False ( apex )
What must be true of a line whose slope is undefined?
The x-coordinate must be the same for all points on the line.
Is a line joining two points not necessarily in the plane containing the two points?
If it is a straight line it must be in the same plane. Otherwise not necessarily.
When two points on a line are used to name the line the points must always be givin in alphabetical order?
No for example Z B You would name this line ZB.
What data must you have to make a line graph?
You can draw a line graph if you have-- the slope of the line and one point on the lineOR-- two points on the line
