Learn it To find the x-intercept, set y = 0. To find the y-intercept, set x = 0. The intercept form $\frac{x}{a} + \frac{y}{b} = 1$ shows both: (a, 0) and (0, b).

Example: Intercepts of $3x + 4y = 24$?

y = 0: $3x = 24$, x = 8.
x = 0: $4y = 24$, y = 6.
Intercept form: $\frac{x}{8} + \frac{y}{6} = 1$.
