Question

Find the slope of the line that passes

through each pair of points.
a. A(1,3), B(4,7)
b. C(3,5), D(2,6)
does anyone know this?

Answer 1

a)
`(4)/(3)`

b) -1

Explanation:

`\boxed{slope = (y1 - y2)/(x1 - x2) }`

where (x₁, y₁) is the first point and (x₂, y₂) is the second point

6a) Slope

`= (7 - 3)/(4 - 1)`

`= (4)/( 3)`

6b) Slope

`= (6 - 5)/(2 - 3)`

`= (1)/( - 1)`

= -1
