which equation represents the line that passes through the points (3, 7) and (-1, -1)?

Liono4ka [1.6K]

points: (3, 7) and (-1, -1)

slope (m) :

$\sf \dfrac{y_2-y_1}{x_2-x_1}$

========

$\hookrightarrow \dfrac{-1-7}{-1-3}$

$\hookrightarrow \dfrac{-8}{-4}$

$\hookrightarrow 2$

Equation:

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

==============

$\rightarrow \sf y-7 = 2(x-3)$

$\rightarrow \sf y = 2x-6+7$

$\rightarrow \sf y = 2x+1$
