Question

Given A(8,3), B(4,8), C(4,4) and D(8,-1) find the slope of AB

Answer 1

Answer:

Step-by-step explanation:

Slope: $\frac{y_2-y_1}{x_2-x_1}$ when the given points are $(x_1,y_1)$ and $(x_2,y_2)$

Plug in A(8,3) and B(4,8)

$=\frac{8-3}{4-8} \\=\frac{5}{-4}\\=-\frac{5}{4}$

Therefore, the slope of AB is $-\frac{5}{4}$.

I hope this helps!
