Question

What is the slope formula of (1,2) and (5,4)

Answer 1

Required Answer:-

Given points:-

• (1,2)
• (5,4)

Here,

• x1=1,x2=5
• y1=2,y2=4

Slope=m

`{:}\longrightarrow`
`\sf m={\frac {y_2-y_1}{x_2-x_1}}`

`{:}\longrightarrow`
`\sf m={\frac {4-2}{5-1}}`

`{:}\longrightarrow`
`\sf m={\frac {2}{4}}`

`{:}\longrightarrow`
`\sf m={\frac {1}{2}}`

`\therefore`
`\sf slope={\frac {1}{2}}`

Answer 2

Slope =
`(1)/(2)`

Explanation:

(x₁ ,y₁) = (1 , 2) & (x₂ , y₂) = (5 , 4 )

Slope
`= (y_(2)-y_(1))/(x_(2)-x_(1))`

`= (4 - 2)/(5 - 1)\\\\=(2)/(4)\\\\=(1)/(2)`
