Slope of (0,1) and (3,0)

Marysya12 [62]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{ \frac{ - 1}{3}}}}}}$

Step-by-step explanation:

Let the points be A and B

Let A ( 0 , 1 ) be ( x₁ , y₁ ) and B ( 3 , 0 ) be ( x₂ , y₂ )

Finding the slope of the points

$\boxed{ \sf{slope = \frac{y2 - y1}{x2 - x1} }}$

$\longrightarrow{ \sf{slope = \frac{0 - 1}{ 3 - 0}}}$

$\longrightarrow{ \sf{slope = \frac{ - 1}{3}}}$

Hope I helped!

Best regards! :D
