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:
This value of x can then be used to find y by substituting 1 with x e.g. in the first equation. The solution of the linear system is (1, 6). You can use the substitution method even if both equations of the linear system are in standard form. Just begin by solving one of the equations for one of its variables.
