Answer 1

Answer:

$\huge \boxed{\bf{y = x - 3}}$

Step-by-step explanation:

Given:-

Take two point:

• (1, -2), (2, -1)

To find:-

• equation of line

Ans:-

~Find slope in two point:

• (1, -2) $\Rarr (x_1, y_1)$
• (2, -1) $\Rarr (x_2, y_2)$

$\sf \to m = \frac{y_2 - y_1}{x_2 - x_1}$

$\sf \to m = \frac{-1 - (-2)}{2 - 1}$

$\sf \to m = \frac{1}{1}$

$\sf \to m = 1$

$\:$

~Find equation:

$\sf \to y - y_1 = m(x - x_1)$

$\sf \to y - (-2) = 1(x - 1)$

$\sf \to y + 2 = x - 1$

$\sf \to y = x - 1 - 2$

$\sf \to y = x - 3$

Answer 2

Answer:

y = x - 3

Explanation:

take two points: (1, -2), (2, -1)

Find slope:

$\boxed{\sf \frac{y_2 - y_1}{x_2 - x_1} }$ where (x1, y1), (x2, y2)

$\sf \rightarrow \dfrac{-1-(-2)}{2-1}$

$\sf \rightarrow 1$

Equation:

y - y1 = m(x -x1)

y - (-2) = 1(x-1)

y + 2 = x - 1

y = x - 3
