WebTo find an equation of a line given the slope and a point. Step 1. Identify the slope. Step 2. Identify the point. Step 3. Substitute the values into the point-slope form, y − y1 = m(x − x1). Step 4. Write the equation in slope-intercept form. Example 3.27 Find an equation of a horizontal line that contains the point (−2, −6). WebA perpendicular line is a straight line through a point. It makes an angle of 90 degrees with a particular point through which the line passes. Coordinates and line equation is the prerequisite to finding out the perpendicular line. Consider the equation of the line is ax + by + c = 0 and coordinates are ( x1, y1 ), the slope should be − a/b.
