How do you find the slope and y-intercept of X and Y?

How do you find the slope and y-intercept of X and Y?

To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’. To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’. In this tutorial, you’ll see how to find the x-intercept and the y-intercept for a given linear equation. Check it out!

How do you find the x and y intercepts given an equation?

To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. For example, lets find the intercepts of the equation y = 3 x − 1 \displaystyle y=3x – 1 y=3x−1. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

How do you find the y-intercept when given two points and the slope?

Steps

  1. Calculate the slope from 2 points. For Example, Two points are (3, 5) and (6, 11)
  2. Substitute the slope(m) in the slope-intercept form of the equation.
  3. Substitute either point into the equation. You can use either (3,5) or(6,11).
  4. Solve for b, which is the y-intercept of the line.
  5. Substitute b, into the equation.

How do you find the x-intercept in slope-intercept form?

We can use the slope-intercept form (y = mx + b). The x-intercept is found by setting y = 0, because that will give us the x-value at which the line crosses the x-axis.

How do you find slope from an equation?

To find the slope of a line given the equation of the line, first write it in slope-intercept form. Use inverse operations to solve for y so that it is written as y=mx+b. Then you can easily see the slope since it is the coefficient of the x variable, or the number in front of x.

How do you calculate slope and intercept?

Finding the y-intercept, Given the Slope and One Point Set up the formula y=mx+b{\\displaystyle y=mx+b}. In the formula, y = the y-coordinate of any point on the line, m = slope, x = the x-coordinate of any point on the line, and b = the y-intercept. y=mx+b{\\displaystyle y=mx+b} is the equation of a line.

How do you calculate X and y intercept?

How to find y intercept with coordinates?

Write down the equation of the line. If you already have the equation of the line,you can find the y-intercept with a little algebra.

  • Substitute 0 for x. The y-axis is a vertical line along x = 0.
  • Solve for y. The answer is the y-intercept of the line. The y-intercept of the line is 4.
  • Confirm by graphing (optional). To check your answer,graph the equation as neatly as you can. The point where the line crosses the y-axis is the y-intercept.
  • Find the y-intercept for a quadratic equation. A quadratic equation includes a variable (x or y) raised to the power of 2.
