The point-slope form of the equation of a straight line is: y y1 = m(x x1). The equation is useful when we know: one point on the line: (x1, y1). m,.
The equation of a line can be written in various ways with each way giving us some information about it. It can even be written with x being the subject of the equation. Answer and Explanation: The equation of a line with a point and slope available is given by ...

Write the equation of the line with slope and y intercept-1. Graph.Suppose that a line has slope m and passes through a fixed point (x_1,y_1) . If the point (x, y) is any other point on the line (Fig. 10), then(y-y_1)/(x-x_1)=m That is,y-y_1=m(x-x_1) (4)...
Example: What is the equation of this line? Start with the "point-slope" formula: y − y1 = m(x − x1) Put in these values: x1 = 1 y1 = 6 m = (2−6)/(3−1) = −4/2 = −2 And we get: y − 6 = −2(x − 1) Simplify to Slope-Intercept (y = mx...
Working with Point-Slope Form What's Point-Slope Form of a Linear Equation? When you're learning about linear equations, you're bound to run into the point-slope form of a line. This form is quite useful in creating an equation of a line if you're given the slope and ...

The slope of a line is a measure of the steepness and direction of the slant of the line. Slope is sometimes expressed as the ratio of the rise of a line, or its vertical change, to the run of the line, or its horizontal change. A steep line will have a slope with a larger abso...
