How do you find the standard form of the equation of a line that goes through the points (0, 5) and (4, 0)?

To find the standard form of the equation of a line given two points, you can follow these steps:

  1. Identify the Points: We have the points (0, 5) and (4, 0).
  2. Calculate the Slope: The slope (m) of a line through two points (x1, y1) and (x2, y2) can be calculated using the formula:

    m = (y2 – y1) / (x2 – x1)


    Substituting the points:


    m = (0 – 5) / (4 – 0) = -5 / 4
  3. Use the Point-Slope Form: Now you can use the point-slope form of a line, which is given by the equation:


    y – y1 = m(x – x1)


    Using point (0, 5):


    y – 5 = -5/4(x – 0)
  4. Simplify to Slope-Intercept Form: Distributing the slope:


    y – 5 = -5/4x


    y = -5/4x + 5
  5. Convert to Standard Form: The standard form of the equation of a line is typically written as Ax + By = C. We can rearrange the equation:


    5/4x + y = 5


    To eliminate the fraction, multiply the entire equation by 4:


    5x + 4y = 20

So, the standard form of the equation of the line that passes through the points (0, 5) and (4, 0) is:

5x + 4y = 20
