Graphing Functions and Examining Coefficients Behavior of Specific Functions Linear Functions: Linear functions are straight lines. Form being examined is y = mx + b.Some Observations:If the slope, m, is positive, the line slants uphill. As the slope gets larger, the uphill slant of the line gets steeper. As the slope gets extremely large (a very big number), … [Read more...] about Graphing Functions and Examining Coefficients
