Math Problem Statement

Rewrite the following equation in standard form: y = 10x - 2.

Solution

The given equation is:

y=10x2y = 10x - 2

We are tasked with rewriting this equation in standard form, which is:

Ax+By=CAx + By = C

Step-by-Step Solution:

  1. Start with the given equation: y=10x2y = 10x - 2

  2. Rearrange the equation so that both xx and yy terms are on the left side: 10x+y=2-10x + y = -2

  3. To ensure that the coefficient of xx is positive, multiply the entire equation by 1-1: 10xy=210x - y = 2

Now, the equation is in standard form: 10xy=210x - y = 2, where A=10A = 10, B=1B = -1, and C=2C = 2. The greatest common factor (GCF) of these values is 1, satisfying the requirements.
