equation of a straight line given two points
How do you find the point-slope form of a line?
The equation of the point-slope form is: y - y 1 = m (x - x 1 ), where (x, y) is an arbitrary point on the line. Let us see how to find the point-slope form. We will derive this formula using the equation for the slope of a line. Let us consider a line whose slope is m. Let us assume that (x 1, y 1) is a known point on the line.
How do you calculate a line passing through points?
To compute the equation of the line passing through points (x1, y1) and (x2, y2): Compute the slope as a = (y2-y1) / (x2-x1). Compute the intercept as b = y1 - a × x1. The equation you need reads y = a × x + b, with a an b computed as above. If x2 = x1, you cannot compute a — the line is vertical and has equation x = x1.
What is the equation of a straight line?
The equation of a straight line is a linear equation in x and y that gives the relation between the coordinate points that lie on that line. The equation of a straight line is usually of the form y = mx + c, where m is the slope of the line and c is its y-intercept. What is the Formula for the Equation of a Straight Line?
How do you find an equation of a line?
We have two options so far for finding an equation of a line: slope–intercept or point–slope. Since we will know two points, it will make more sense to use the point–slope form. But then we need the slope.
