Final Answer:
For s = r0, rearranging for r gives: r = s / 0.
For y = mx + b, rearranging for m gives: m = (y - b) / x.
Step-by-step explanation:
To rearrange the formula s = r0 for r, divide both sides of the equation by 0: r = s / 0. This expression becomes undefined since division by 0 is not possible in mathematics. Therefore, the equation s = r0 does not have a valid solution for r when rearranged.
For the equation y = mx + b representing a linear equation in slope-intercept form, to isolate the slope (m), rearrange the formula. Begin by subtracting b from both sides to get: y - b = mx. Then, divide both sides by x to solve for m: m = (y - b) / x. This rearrangement isolates the slope (m), showing that the slope of a line (m) is the change in y divided by the change in x, represented as the rise over the run in a Cartesian coordinate system.
This rearrangement helps in understanding how changes in x and y affect the slope of a linear equation and how the slope-intercept form of a line can be used to graph lines or analyze linear relationships between variables.
