In 2008, Harvard Stem Cell Institute principal faculty member Kevin Eggan first raised the possibility of using ALS patient-derived stem cells to better understand the disease and identify therapeutic targets for new drugs.
If f(x) is linear, the graph of y = f(x) is a straight line. The parameter m in the first two formulas is the slope of this line. In the general form, the slope is -A/B if B 0 and infinite if B = 0. In the slope-intercept form, the parameter b is the y-intercept. In the point-slope form, the point (x0, y0) is a point on the line y = f(x). Any point (x0, y0) on the line will lead to an equivalent equation. We will frequently have to perform the following calculations with linear equations:
Determine the value of the slope of a line from a table or a graph. Proportional Relationships. Determine whether a linear function is a direct variation. Solve problems involving direct variation. Compare proportional and non-proportional linear functions in the form of a table, graph and equation. Slope Intercept Form. Analyze a graph to determine slope and y-intercept. Graph a linear function using the slope and y-intercept. Write a linear equation in slope-intercept form given the slope and y-intercept. Standard Form. Analyze a linear graph to determine the intercepts. Write linear equations in standard form to model real world scenarios. Determine and interpret the intercepts of a linear function from an equation in standard form.
