Practice Intersection (Geometric) in Math

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

The set of all points where two or more geometric objects (lines, planes, curves) meet or cross each other.

Where two roads crossβ€”that single crossing point is their intersection.

Example 1

easy
Find the intersection point of lines \ell_1: y = 3x - 2 and \ell_2: y = -x + 6.

Example 2

medium
Find the intersection point(s) of line y = x + 3 and circle x^2 + y^2 = 25. Classify the intersection (secant, tangent, or no intersection).

Example 3

easy
Do lines y = 2x + 3 and y = 2x - 5 intersect? Explain why or why not.

Example 4

hard
Find the intersection of the two circles: C_1: x^2 + y^2 = 25 and C_2: (x-4)^2 + y^2 = 9.
