Point slope form is a general form for linear equations. In other words, it is used to define a particular line compactly.Point slope calculator is an online tool developed to find the equation of a straight line using the slope and point on that line or two points. What purpose does it serve? It is used principally to indicate the gradient of a line. An equation for a straight line with gradient m and intercept c is y = mx + c on the y-axis. C is commonly referred to as the intercept on the y-axis. Lines have a general form of y = mx + c, where m is the gradient, and c is the value where the line crosses the y-axis. Solution: The given equation 13x –13 y + 12 = 0 can be represented in slope-intercept form as:Īlso, the above equation can be reframed in intercept form as: (2) An equation of a line is represented by 13x – 13y + 12 = 0. Thus, x-intercept = -3/2 and y-intercept = 1/2. Using slope-intercept form, the given equation 2x – 6y + 3 = 0 can be expressed as:įurthermore, we can reframe the above equation in intercept form as follows: Determine the slope and both intercepts of the equation of a line 2x – 6y + 3 = 0. The following examples will help you better understand this concept: Slope (m) of a non-vertical line passing through the points (x1, y1 ) and (x2, y2 )Įquation of the line passing through the points (x1 ,y1 ) and (x2, y2 )Įquation of line with slope m and intercept cĮquation of line with slope m makes x-intercept d. The following is a summary of the straight line formulas we have discussed so far: The following is an illustration of straight-line formulas in different forms: Straight Line Formulas Two variables of the first degree can be used to derive a line in the general equation.Ī, B ≠ 0 where A, B, and C are constants belonging to real numbers.Ī straight line is always the result of representing the equation geometrically. ( Ax2 + By2 + C)>0, else these points would lie on the opposite sides of the line Ax + By + C = 0
