In this video lesson we will learn how to graph a linear function in standard form using the x and y intercepts. We will discover that standard form is Ax + By = C where A, B, and C MUST all be integers - meaning they cannot be fractions or decimals. We will also learn that both A and B cannot be equal to zero, however, if either A or B is zero, this will result either a horizontal line or a vertical line. We will learn that horizontal lines cross the y-axis, have a y-intercept, and are written in the form y=b where b represents the y-intercept. We will learn that vertical lines cross the x-axis, have an x-intercept, and are written in the form x=a where a represents the x-intercept. We will also learn how to find the x and y-intercepts of a linear function written in standard form. We will discover that if we evaluate the equation for y=0 or find the solution (a, 0) we will find the x-intercept. Then, we will learn that if we evaluate the equation for x=0 or find the solution (0, b) we will find the y-intercept. Since we will have found two solutions or points on the linear function, we can graph the linear function using the intercepts. We will also graph a real world linear function and interpret the x and y intercepts relative to the given situation. Student practice problems are embedded in the lesson and include modeled exemplar solutions.
