Find the Equation of a Line Given the Slope and a Point on the LineUsing the slope-intercept equation of a line is possible when you know both the slope (m) and the y-intercept (b), but what if you know the slope and just any point on the line, not specifically the y-intercept?
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)...
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,.

Find the equation of the line in slope-intercept form. The line through {eq}(-3, -2) {/eq} with slope {eq}-\frac{1}{2} {/eq}.Equation of the Line:We can find the equation of a line with the slope and a point by applying the following steps:...
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...
Point-Slope Equation of a Liney –y1 = m(x –x1), where m is the slope and (x1, y1) is a point on the line. Point-slope is the form used most often when finding the equation of a line.Movie Clips (with narration)Point and Slope: How to find the equation of a line (4.13M...
Simply identify if the equation or graph is that of a horizontal or vertical line and then the slope is known. How do you find horizontal and vertical lines? To find horizontal or vertical lines given an equation, simply locate a point that lies on the line and then draw either a ...
Want to find the slope-intercept form of a line when you're given a point on that line and another line parallel to that line? Remember, parallel lines have the same slope. If you can find the slope of that parallel line, you'll have the slope...
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...
