Practice Parameter in Math

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

Quick Recap

A fixed constant that defines a specific member of a family of functions or equations, often denoted by early-alphabet letters.

In y = mx + b, m and b are parameters โ€” different values give different lines.

Example 1

medium
In the family of lines y = mx + 3, what role does m play?

Example 2

hard
For what value of the parameter k does kx + 2 = 6 have the solution x = 2?

Example 3

medium
In the family of lines y = mx + 3, find the slope when the line passes through (2, 7).

Example 4

easy
In y = 2x + b, is b a variable or a parameter?

Example 5

medium
The quadratic f(x) = x^2 - px + 4 has a zero at x = 1. Find p.
