Which formula can be used to find the slope of a line from two points (x1,y1) and (x2,y2) ?
1 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
2 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
3 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
4 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 to find the slope of a line from two points (x1,y1) and (x2,y2) is:
4. The slope is given by the formula: (y2 - y1) / (x2 - x1)
The correct formula to find the slope of a line from two points (x1,y1) and (x2,y2) is:
4) Start Fraction y2 − y1 over x2 − x1 End Fraction
The formula that can be used to find the slope of a line from two points (x1, y1) and (x2, y2) is option 4:
Slope = (y2 - y1) / (x2 - x1)
This formula represents the change in the y-coordinates divided by the change in the x-coordinates between the two points. The numerator (y2 - y1) gives the difference in the y-coordinates, while the denominator (x2 - x1) gives the difference in the x-coordinates. By dividing these two differences, we obtain the slope of the line passing through these two points.
