Question

Calculate the slope of the line given the points (2,1) and (1,-4)

Answer 1

`\Huge \boxed{5}`

Explanation:

Slope formula:

`\displaystyle (y_2-y_1)/(x_2-x_1)`

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

`\Large\textnormal{Therefore, the slope is 5, and the correct answer is 5.}`

`\Large\textnormal{Hope this helps!}`

Answer 2

The equation for the slope of a line is:

y2-y1/x2-x1

So:

-4-1/1-2 = -5/-1 =5

The slope of the line is 5.
