How do you find the value of y with a given slope?

How do you find the value of y with a given slope?

Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 – y2] / [x1 – x2]. If you know x, you can solve for y to find the y value for the slope of the line.

How do you find the y value of two points?

Steps to find the equation of a line from two points:

  1. Find the slope using the slope formula.
  2. Use the slope and one of the points to solve for the y-intercept (b).
  3. Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.

What is the y-intercept of (- 3 7?

Hence, y -intercept is −23 .

What is the y-intercept of (- 6?

Using the slope-intercept form, the y-intercept is 6 .

What is a value of y?

1y=15.735. y=115.735≈0.064.

How do you find y in a equation?

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 y-intercept given two points?


  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.

Which equation represents the line that passes through (- 6 7 and (- 3 6 )?

The slope of a line joining the two points is y2-y1 / x2-x1 which in this case is 6-7 / -3 – -6) = – 1/3. The slope-intercept form of a line is y =mx +b where m is the slope and b in the y intercept.

What is the slope of Y − 6?

The line crosses the y-axis at 6 , as the line is always at that value. As it is a horizontal line, the slope is zero.

How do you find slope when given an equation?

Use the point-slope formula to find the equation. No matter how you got here, you should have 1 point on the line and the slope of the line. The formula to use is y – y1 = m(x – x1). Using the slope m you just calculated and one of the given coordinates on the line, plug the numbers into the equation.

How to find slope and y intercept?

Write down the slope and point. The slope or “rise over run” is a single number that tells you how steep the line is.

  • Learn the slope-intercept form of an equation. Any straight line can be written as an equation in the form y = mx+b.
  • Substitute the slope in this equation.
  • Replace x and y with the coordinates of the point.
  • Solve for b.
  • How do you find the slope and the y intercept?

    In general, the slope intercept form assumes the formula: y = mx + b. m is the slope (lesson on slope ) mnemonic : ‘m’ means ‘move’ b is the y -intercept ( lesson on the y-intercept ) mnemonic : ‘b’ means where the line begins.

    How do you calculate slope?

    Find two points on the line.

  • Count the rise (How many units do you count up or down to get from one point to the next?) Record this number as your numerator.
  • Count the run (How many units do you count left or right to get to the point?) Record this number as your denominator.
  • Simplify your fraction if possible.
