Find the slope. of the line
two points
A(0,4), B(4,0)​

Answer 1

Answer:

slope = 0 & y = 0 is the line joining the points(2,0) and(-2,0) Find the inclination of a line whose slope is: (i) 1 (ii) -1 (iii) √3

Answer 2

Correct question :

Find the slope of the line passing through two points A(0,4), B(4,0).

Solution :

We know that :-

$\sf slope \: of \: line : \\ \\ \boxed{\tt \rightarrow \: \dfrac{y_2-y_1}{ x_2-x_1} }$

Now, we have to find out slope of the line passing through two points A(0,4), B(4,0).

$\rm Here : \\ \\ \rm x_1 = 0 \\ \\ \rm x_2 = 4 \\ \\\rm y_1 = 4 \\ \\ \rm y_2 = 0$

$\tt \rightarrow \dfrac{0-4}{ 4-0 } \\ \\ \tt \rightarrow \dfrac{-4}{ 4} = - 1$

Answer :

The slope of the line passing through two points A(0,4), B(4,0). = -1

$\underline { \large Additional-Information }$

slope (m) of line ax + by + c = 0is :

$\boxed{ \large \sf m = \frac{ - a}{b} }$

$\sf \: Distance \: between \: two \: points \: (x_1 , y_1) \: and \: ( x_2 , y_2) : \\ \\ \tt \longrightarrow \sqrt{{ {(x_2 - x_1)}^{2} + (y_2 - y_1)}^{2} }$
