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:
And look what kind of line it is; it is a straight line! If you are given a linear function, there are two ways to work with it. You can use algebra and calculate your answers or you can graph the function and use the graph to get your answer. Look at the graph above for the function y = 2x.
