Writing equations from any two points Let's write the equation of the line that passes through (2,5) (2,5) and (4,9) (4,9) in slope-intercept form. 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. culligan peak ice machineFinding the equation for a line is a common problem in geometry and trigonometry.

Step 2: Click the blue arrow to submit and see the result! WebTo find where y=1/2x+5 and the original line y=-2x intersect, set them equal to each other. Let y in both of the equations equal the same value. You are doing this because at the two lines' point of intersection, both lines will share the same x and y value. So, let y=1/2x+5 equal y=-2x. That means -2x = 1/2x+5 0= 5/2x +5 -5 = 5/2x -2 =x

WebHow do you find the equation of a line? To find the equation of a line y=mx-b, calculate the slope of the line using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line. Substitute the value of the slope m to find b (y-intercept). 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
