Exam (elaborations) Sophia Milestone 3 College Algebra with Correct answers.( best of 2021) Sophia Milestone 3 College Algebra with Correct answers.( best of 2021) The form is called slope-intercept form. To identify the equation of this graph in slope-intercept form, we need to identify two parts to the line: its slope, noted by the variable ; and its y-intercept, noted by the variable . Let's start by finding the y-intercept. We can easily identify the y-intercept by examining when the line crosses the y-axis. This occurs at so this means that is the variable in the equation. Now that we have the y-intercept, we can find the slope, . We need to calculate the rise over run between two points on the graph. First, let's identify two points. We can use the y-intercept at and another point on the line, . To find the slope, use the slope formula which states that the slope is the difference in values divided by the difference in values. Once we have the points plugged into the formula, we can evaluate both the numerator and denominator. In the numerator, minus is . In the denominator, minus is . Then, simplify the fraction. The fraction simplifies to , which is the slope of the equation. We can put both parts together to find the full equation. The y-intercept is at and the slope is , so the equation of the line i
