Slope Formula:
m=(y_2-y_1)/(x_2-x_1)

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Explanation:

Step 1: Define

y-intercept (0, -4)

Random Point (4, 1)

Step 2: Find slope m

  1. Substitute:
    m=(1+4)/(4-0)
  2. Add/Subtract:
    m=(5)/(4)

Step 3: Write Equation

Substitute

y = 5/4x - 4
