Question

Which formula can be used to find the slope of a line from two points (x1,y1) and (x2,y2) ?

y2+y1x2+x1
Start Fraction y subscript 2 baseline plus y subscript 1 baseline over x subscript 2 baseline plus x subscript 1 baseline End Fraction

y2y1−x2x1
Start Fraction y subscript 2 baseline over y subscript 1 baseline End Fraction minus Start Fraction x subscript 2 baseline over x subscript 1 baseline End Fraction

x2−x1y2−y1
Start Fraction x subscript 2 baseline minus x subscript 1 baseline over y subscript 2 baseline minus y subscript 1 baseline End Fraction

y2−y1x2−x1
Start Fraction y subscript 2 baseline minus y subscript 1 baseline over x subscript 2 baseline minus x subscript 1 baseline End Fraction

The correct formula is:

Start Fraction y subscript 2 baseline minus y subscript 1 baseline over x subscript 2 baseline minus x subscript 1 baseline End Fraction

Answer 2

[AI-generated answer — Step-by-Step Bot]

The correct formula to find the slope of a line from two points (x1,y1) and (x2,y2) is:

Start Fraction y subscript 2 baseline minus y subscript 1 baseline over x subscript 2 baseline minus x subscript 1 baseline End Fraction

This formula represents the change in y-coordinates divided by the change in x-coordinates, which gives the slope of the line passing through the two points.

The correct formula to find the slope of a line from two points (x1, y1) and (x2, y2) is:

Start Fraction y subscript 2 minus y subscript 1 over x subscript 2 minus x subscript 1 End Fraction

This formula represents the change in y-coordinates divided by the change in x-coordinates between the two points. By subtracting the y1 value from the y2 value and subtracting the x1 value from the x2 value, you calculate the differences in the coordinates. Then, dividing the y-coordinate difference by the x-coordinate difference gives you the slope of the line passing through the given points.
