How can you use a scatter plot to find an equation of a trend line?
By finding the line of best fit and using the straight line equation formula.
Does the trend line always pass through every point on a scatter plot?
No. When you draw a best line of fit on the scattered plot, the line would not be straight.
When we plot all the points that satisfy an equation or inequality we it?

How do you find the solution of a quadratic equation graphically?
You write the equation in such a way that you have zero on the right side. Then you graph the expression on the left side of the equal sign, and check where it touches the x-axis. Note that this method works for most common equations.
How do you plot y equals -x into a graph?
y=-x Draw a straight line with slope -1 passing through (0,0). Or, plot (x,y) coordinates that satisfy the equation, and connect the dots.
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.
How can you use a scatter plot to find an equation of a trend line?
By finding the line of best fit and using the straight line equation formula.
What is a scattered plot being math related?
A scattered plot is like a graph with a whole lot of dots as data. It tells if the data is almost the same or if it's going down the path all together.
What is the definition of graph of an equation?
Plot the solution of the equation for various variables in the equation
When we plot all the points that satisfy an equation or inequality we do what to it?
Graph it (the equation).
How do you plot the graph of a quadratic equation?
Just like any other equation, you can set up a table of x values, and calculate the corresponding y values. Then plot the points on the graph. In this case, it helps to have some familiarity with quadratic equations (you can find a discussion in algebra books), and recognize (from the form of the equation) whether your quadratic equation represents a parabola, a circle, an ellipse, or a hyperbola.
Write an equation for the scatter plot below. Then, use the equation to make your predictions?
Umm nobody can answer this question because we don't know what "the scatter plot below" is.
Does the trend line always pass through every point on a scatter plot?
No. When you draw a best line of fit on the scattered plot, the line would not be straight.
How do you write a linear equation for a scatter plot?

What should you use to find the equation for a line of fit for a scatter plot?
Least squares regression is one of several statistical techniques that could be applied.
