Web26 de ene. de 2024 · Explanation: An equation is considered linear, if it is in the form of. y = mx + b. where m is the slope of the equation, and b is the y-intercept. Notice how here, x can only be to the power of 1. In here, the conditions are just simply: m,b ∈ R. Some examples include y = 5x + 4, y = x − 2, y = 0, and even some like x = 1. Webwhere and are real numbers, and not both zero. This means that for an equation to be linear, the following must be satisfied: a. The exponents of x and y must be both 1. b. The variables must not appear in the denominator. c. No square roots, cube roots, etc. for the variables. Let’s Discuss!
