There is a fourstep process to determine the equation of the line, with an optional fifth step if you need to put the equation in "standard form".
Often, these questions ask you to put the equation in "standard form" to complete the problem. This is the form Ax + By = C, where A, B, and C are all whole numbers and A is positive. For this question, we'd multiply both sides by 5, then move the x term to the left side:
That would be the final answer. Cheers,
