Question

The slope of the line passing through the points (7,5)and(21,15) is

Answer 1

y=
`(5)/(7)`x+0 is the equation.
`(5)/(7)` is the slope.

Answer 2

The slope is
`(5)/(7)`

Explanation:

Since, the slope of a line that passes through the points
`(x_1,y_1)` and
`(x_2,y_2)` is,

`m=(y_2-y_1)/(x_2-x_1)`

Thus, the slope of the line passes through the points (7,5) and (21,15) is,

`m=(15-5)/(21-7)`

`=(10)/(14)`

`\implies m=(5)/(7)`
