Equation of Straight Line Once a line of best fit has been placed upon a scatter graph it is straightforward to find the equation. The general equation of a straight line is: y=mx+c Wheremis the slope (gradient) of the line andcis they-intercept. To obtain the gradient, find two point...
How do you find the equation for the line of the best fit of the scatter diagram? What is a linear equation? Find the scalar equation of the line perpendicular to 3x -y+7=0 passing through (2,-3). Give the equation of a line that passes through the points (2,4) and (-2, 6)...
