Question

What is the slope for (2, -1) and (3,1)

Answer 1

Answer: 2

Step-by-step explanation:

m = y2 - y1 /   x2- x1

where slope is m,

so in this case it would be

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

m=2/1

m=2

Note that you can do it either way

Answer 2

To find the slope (m), use the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$        and plug in the two points

(2, -1) = (x₁, y₁)

(3, 1) = (x₂, y₂)

[lines usually go from left to right, so the point furthest to the left is the 1st point]

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{1-(-1)}{3-2}$     [two negative signs cancel each other out and become positive]

$m=\frac{1+1}{3-2}$

$m=\frac{2}{1}$

m = 2
