Question

What is the slope formula of (4,2) and (7, 6.5)

Answer 1

Suppose the given coordinates are represented as,

`\begin{gathered} (x_1,y_1)=(4,2) \\ (x_2,y_2)=(7,6.5) \end{gathered}`

Then, the formula for slope can be expressed as,

`\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ m=(6.5-2)/(7-4) \end{gathered}`

Solving it,

`m=(4.5)/(3)=1.5`

The slope is 1.5.

The formula of (10, 8) anjd (-5,8) is

`m=(8-8)/(-5-10)`
