Question

Hiii I need help with this question!! 1.10.4 TEST coordinate geometry!

Answer 1

Formula

$\boxed{\sf Slope(m)=\dfrac{y_2-y_1}{x_2-x_1}}$

Solution:-1

• (5,7)
• (-4,-2)

$\\ \sf\longmapsto m=\dfrac{-2-7}{-4-5}$

$\\ \sf\longmapsto m=\dfrac{-9}{-9}$

$\\ \sf\longmapsto m=1$

Solution:-2

• (1,3)
• (1,-10)

$\\ \sf\longmapsto m=\dfrac{-10-3}{1-1}$

$\\ \sf\longmapsto m=\dfrac{-13}{0}$

$\\ \sf\longmapsto m=0$
