What is the slope of the line with points (2, -1) and (4, 1) ?

–1/2
–2
1/2
2

The correct answer is: –1/2

To find the slope of a line, we use the formula (y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are the coordinates of the two given points. In this case, that would be (2, -1) and (4, 1). Plugging in the values, we get (1-(-1))/(4-2) = 2/2 = 1. Therefore, the slope of the line is 1, which is equivalent to 1/1. The incorrect options are - B: –2, which is the y-value difference divided by the x-value difference in the reverse order. - C: 1/2, which omits the negative sign and is also the y-value difference divided by the x-value difference in the reverse order. - D
