Question

What is the slope of the line (2,3) (1,-2)?

a- -5
b- -1/5
c- 5
d- 1/5

Answer 1

c is the answer. (Assuming that's a positive 5)

Explanation:

You would use the slope formula: (y1 - y2)/(x1-x2).

Plugging in gives

(3--2)/(2-1)

(3+2)/(2-1)

which simplifies to:

5/1

= 5

Hope this helps!

Answer 2

The correct option is C. 5

Explanation:

Points to remember

slope of the line passing through the point (x₁, y₁) and (x₂, y₂) is given by

Slope m = (y₂ - y₁)/(x₂ - x₁)

To find the slope of the given line

Here (x₁, y₁) = (2, 3) and (x₂, y₂) = (1, -2)

Slope m = (y₂ - y₁)/(x₂ - x₁)

= (-2 - 3)/(1 - 2)

= (-5)/(-1)

= 5

Therefore the slope of given line is 5

The correct option is C. 5
