How Will This Worksheet on "Write Point-Slope Form Given Slope and a Point" Benefit Your Student's Learning?

  • Demonstrates how a point and slope define a straight line.
  • Helps find the rate of change or predict situations based on initial conditions.
  • Enhances algebra skills and orientation towards math tasks.
  • Clearly shows number connections, making it easier to explain ideas.

How to Write Point-Slope Form Given Slope and a Point?

  • Let the slope be \( m \) and the point be \((x_1, y_1)\).
  • The point-slope form is: \( y - y_1 = m(x - x_1) \).
  • Replace \( m \) with the given slope.
  • Replace \( x_1 \) and \( y_1 \) with the coordinates of the given point.
  • Expand and simplify the equation to make it look cleaner if needed.

Solved Example

Q. A line with a slope of 99 passes through the point (9,9)(9,9). What is its equation in point-slope form?
Solution:
  1. Define Point-Slope Form: Point-slope form is yy1=m(xx1)y - y_1 = m(x - x_1), where mm is the slope and (x1,y1)(x_1, y_1) is the point the line passes through.
  2. Identify Slope and Point: We know the slope mm is 99 and the point is (9,9)(9,9), so we plug these values into the point-slope form.
  3. Substitute Values into Formula: y9=9(x9)y - 9 = 9(x - 9) is the equation in point-slope form.

About Worksheet

Algebra 1
Linear Relationship

To write the point-slope form of a line when given a slope and a point, use the formula  `y - y_1 = m(x - x_1)`. Here, `m` represents the slope, and `(x_1, y_1)` is the point given. For example, if the slope ‘`m`’  is `2` and the point is `(3, 4)`, you substitute these values into the formula: `y - 4 = 2(x - 3)`. This equation shows how the line relates to the given point and slope, making it clear how the line moves through that specific point with the specified slope.
