y mx + b y 4x + 6 If you need to calculate the slope using two points, use slope calculator. Point slope form is a variation of the slope formula: Slope m (y2-y1)/(x2-x1) If you mulitply both sides by (x2-x1), then you get point slope form: (y2-y1) m(x2-x1) Then, they swab a couple of variables to clarify the variables that stay. Step 3: Write the equation in slope-intercept form (y mx + b) Now that we know m 3 and b -5, we. Well pick the first point (4,7) and plug in 4 for x and 7 for y. It does not matter which point you choose. Plug the slope and the x and y of one of the given points into y mx + b, then solve for b. Solve for the y-value of the y-intercept ( b ). Remember, the slope is equal to the change in y divided by the change in x (rise over run). For example, if you wanted to generate a line of best fit for the association between height and shoe size, allowing you to predict shoe size on the basis of a person's height, then height would be your independent variable and shoe size your dependent variable). b 6 m 4 Step 2: Write the slope form equation and place the values. Pick one of the points on the line and use the x and y values to find b. Find the slope-intercept form of a line using. To begin, you need to add paired data into the two text boxes immediately below (either one value per line or as a comma delimited list), with your independent variable in the X Values box and your dependent variable in the Y Values box. This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X. Choose the mode 'Line equation is ax + by + c 0'. To calculate the x-and y-intercepts along with the lines slope from its general equation. This line equation from two points calculator will help you write down the equation of a line passing through any pair of points.Scroll down to find an article explaining how to determine the slope-intercept linear equation as well as the standard form linear equation from any two points in 2D space. The line of best fit is described by the equation ลท = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). You can use this y-intercept calculator in three modes. This simple linear regression calculator uses the least squares method to find the line of best fit for a set of paired data, allowing you to estimate the value of a dependent variable ( Y) from a given independent variable ( X).
