  • y = mx+c
CISCE: Class 10

Formula: Slope–Intercept Form

When slope and y-intercept are given

y = mx + c

  • m = slope

  • c = y-intercept (value of y when x = 0)

CISCE: Class 10

Formula: Point–Slope Form

When the slope and one point are given

y − y1 = m(x − x1)

CISCE: Class 10

Formula: Two-Point Form

When two points are given

\[\frac{y-y_1}{x-x_1}=\frac{y_2-y_1}{x_2-x_1}\]
