WebThese lines are written in the form y = mx + b, where m is the slope and b is the y-intercept. We know from the question that our slope is 3 and our y-intercept is –5, so plugging these values in we get the equation of our line to be y = 3x – 5. m = 3 and b = –5 Report an Error Example Question #3 : How To Find The Equation Of A Line WebMar 16, 2011 · Given two points on a line, we can write an equation for that line by finding the slope between those points, then solving for the y-intercept in the slope-intercept equation y=mx+b. In this …

Determining the equation of a straight line - BBC Bitesize

WebThe equation of a horizontal line is y = b where b is the y-intercept. Since the slope of a horizontal line is 0, the general formula for the standard form equation, y = mx + b becomes y = 0x + b y = b. Also,since the line is horizontal, every point on that line has the exact same y value. This y-value is therefore also the y-intercept. WebPoint-slope Form of an Equation of a Line. The point-slope form of an equation of a line with slope m and containing the point (x1, y1) is: y − y1 = m(x − x1) We can use the point-slope … cindy cepko weichert realtors

WebJun 29, 2024 · Finding the Equation Quickly for Vertical or Horizontal Lines Download Article 1 Take one good, quick look at the number on the x or y axis. If the line is vertical, look at the x-intercept. If the line is horizontal, look at the y-intercept. The equation for these types of lines are different from the y=mx+c structure. WebJul 22, 2024 · A linear equation or equation of a line has the following form: y = mx + b m: slope of the line; m = Δx/Δy b: y-intercept, which is where the line crosses the y-axis; b = yi … Finding the equation for a line is a common problem in geometry and trigonometry.
