WebJul 1, 2024 · For each set of data, plot the points on graph paper. Make your graph big enough and use a ruler. Then "by eye" draw a line that appears to "fit" the data. For your line, pick two convenient points and use them to find the slope of the line. Find the \(y\)-intercept of the line by extending your line so it crosses the \(y\)-axis. WebNov 28, 2024 · Step 4: The following screen shows up. To the calculator, a is the slope and b is still the y−intercept. Therefore, the equation of the line is y=267.4x+2939.55. Step 5: If you would like to plot the line on the scatterplot, press. Y= and enter in the equation from Step 4: y=267.4x+2939.55. Press GRAPH.

WebLinear Scatter Plot: In mathematics, a scatter plot is simply a graph of plotted data points. When the data points of a scatter plot seem to take on a linear pattern, we call it a linear scatter plot. When this is the case, we can find the equation of the line that models the data points in the slope-intercept form using a few steps. fhingi
