Question

Find the slope and reduce of p=(3/4,1 1/4) q=(-1/2,-1)

Answer 1

`\bf slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-1-(1)/(4)}{-(1)/(2)-(3)/(4)}\quad \cfrac{\leftarrow LCD=4}{\leftarrow LCD=4} \\\\\\ \cfrac{(-4-1)/(4)}{(-2\cdot 1-3)/(4)}\implies \cfrac{(-5)/(4)}{(-5)/(4)}\implies \cfrac{-5}{4}\cdot \cfrac{4}{-5}\implies 1`
