how to figure out x intercept from y mx b To find the x intercept of a line of the form y mx b substitute y 0 Example To calculate the x intercept of any line for example the line y 2x 4 put y 0 in the equation of a line Solution 0 2x 4 4 2x 2 x So the x intercept of the line y 2x 4 is 2 Similarly by substituting x 0 we can find the y intercept y 2 0 4
To find the x intercept you would substitute in the value of 0 for y variable and then solve for the x variable Example y 2x 6 0 2x 6 6 2x 6 2 2x 2 3 x 3 0 The y intercept Answer link The coordinates of a line or point on the x axis will always have a y coordinate of 0 Solution The required equation of the line is y mx b Using the formula for slope m change in y change in x dfrac y 2 y 1 x 2 x 1 7 3 3 1 4 2 m 2 To find the y intercept b we consider any one of the coordinates

FAQ The slope intercept form calculator will teach you how to find the equation of a line from any two points that this line passes through It will help you to find the coefficients of slope and y intercept as well as the x Writing Exercises Self Check Learning Objectives By the end of this section you will be able to Recognize the relation between the graph and the slope intercept form of an equation of a line Identify the slope and y intercept form of an equation of a line Graph a line using its slope and intercept
In the equation y mx b m is the slope of the line and b is the intercept x and y represent the distance of the line from the x axis and y axis respectively The value of b is equal to y when x 0 and m shows how steep the line is The equation of a straight line is usually written this way y mx b or y mx c in the UK see below What does it stand for y how far up x how far along m Slope or Gradient how steep the line is b value of y when x 0 How do we find m and b b is easy just see where the line crosses the Y axis
