Question

What is the slope of the line that passing through point (2,3) and (-2,5)?

Answer 1

Answer:

$\displaystyle \boxed{-\frac{1}{2}}$

Step-by-step explanation:

Slope formula:

     ↓

$\displaystyle \frac{Y_2-Y_1}{X_2-X_1}$

$\displaystyle Y_2=5\\\displaystyle Y_1=3\\\displaystyle X_2=(-2)\\\displaystyle X_1=2$

$\displaystyle \frac{5-3}{(-2)-2}=\frac{2}{-4}=\frac{2\div2}{-4\div2}=\frac{1}{-2}=-\frac{1}{2}$

Therefore the slope is -1/2.

-1/2 is the correct answer.

Hope this helps!
