c = 3 which is the value of y when the graph crosses the y-axis, that is, when x = 0. (b) In the equation 3x − 4 y = 2, we rewrite the equation with y as the subject of the formula in order to find the value of m and c. 3x−4y=2⇔3x=2+4y⇔3x−2=4y⇔...
To make everything as clear as possible – we are going to find a straight line with a slope,a, and intercept,b. The formula for the line of the best fit with least squares estimation is then: y = a · x + b. As you can see, the least square regression line equation is no di...
Find the slope m of the line of best fit using the formula. 4. Compute the y -intercept of the line by using the formula: 5. Use the slope m and the y -intercept to form the equation of the line. 6. Obtain the straight line equation Y=mX+b and plot the scatterplot. Program...
