Question

Problem 1) Which of the equations below could be used to calculate the slope of a line?
m=y2-y1/x2-x1

Answer 1

The equation you've written for calculating the slope of a line is almost correct, but it should include parentheses to clarify the operation. The correct formula for the slope \( m \) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is:

\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]

Using parentheses helps to avoid confusion about the order of operations. Make sure to always write the formula with the fraction clearly indicated.
