Question

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

Answer 1

`\displaystyle \boxed{-(1)/(2)}`

Explanation:

Slope formula:

↓

`\displaystyle (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 (5-3)/((-2)-2)=(2)/(-4)=(2/2)/(-4/2)=(1)/(-2)=-(1)/(2)`

Therefore the slope is -1/2.

-1/2 is the correct answer.

Hope this helps!
