Question

The points represented by the table lie on a line. How can you find the slope of the line from the table? What is the slope of the line? Х 2 4 6 8 y 5 1 -3 -7

Answer 1

The given table is

x 2 4 6 8

y 5 1 -3 -7

The formula for determining the slope of a line is expressed as

slope = (y2 - y1)/(x2 - x1)

From the table,

x1 = 2, x2 = 4

y1 = 5, y2 = 1

Slope = (1 - 5)/(4 - 2)

Slope = - 4/2

Slope = - 2
