Text Interpret coefficient -6 from the regression equation. Since the slope of a horizontal line is 0 the general formula for the standard form equation y mx b becomes y 0x b y b. The reason for recasting it in the form.
Subtract b b from both sides of the equation.
M 5 or 51 b 6. The standard form of y mx b becomes y 2x b now you take the point xy 35 that is on the line has to be on the line and replace x and y in the equation with it. The equation of any straight line called a linear equation can be written as. Substitute the known values into the slope formula and simplify if necessary.
