Questions & Step-by-Step Solutions

If a line has the equation y - 3 = 4(x - 1), what is its slope?
  • Step 1: Identify the equation given: y - 3 = 4(x - 1).
  • Step 2: Recognize that this equation is in point-slope form, which is generally written as y - y1 = m(x - x1).
  • Step 3: In the point-slope form, 'm' represents the slope of the line.
  • Step 4: From the equation y - 3 = 4(x - 1), we can see that the value of 'm' is 4.
  • Step 5: Therefore, the slope of the line is 4.
  • Point-Slope Form – The equation of a line in the form y - y₁ = m(x - x₁) where m is the slope.
  • Identifying Slope – Understanding how to extract the slope from the point-slope form of a line.
