Solution:

Step-1: Find the slope of the line.

Formula: Rise/Run = y₂ - y₁/x₂ - x₁

  • y₂ - y₁/x₂ - x₁ = Slope
  • => -2 - (-1)/4 - 0 = Slope
  • => -2 + 1/4 - 0 = Slope
  • => -1/4 = Slope

Step-2: Find the y-intercept of the line.

The y-intercept of the line is the point that intersects the y-axis.

  • => y-intercept = -1

Step-3: Create the equation.

  • => y = (m)x + (b)
  • =>
    y = -(1)/(4) x - 1

Y=1/4x - 1 since the y intercept is at -1
