Question

Slope of the line through the points (2,1) and (4,2) is

Answer 1

slope =
`(1)/(2)`

Explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (4, 2)

m =
`(2-1)/(4-2)` =
`(1)/(2)`

Answer 2

`\huge\boxed{(1)/(2)}`

We can use
`(y_2-y_1)/(x_2-x_1)` to find the slope, where
`(x_1, y_1)` and
`(x_2, y_2)` are both points.

Plug in the values.
`(2-1)/(4-2)`

Subtract.
`(1)/(2)`
