Question

Find the slope of the line that passes through the points (1, -3) and (2, -1). a.) one half b). negative one half c). -2 d).2

Answer 1

Answer:

d).2

Step-by-step explanation:

Use the following equation:

slope (m) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (1 , -3)

(x₂ , y₂) = (2 , -1)

Plug in the corresponding numbers to the corresponding variables:

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

Simplify. Combine like terms. Remember to follow PEMDAS. Remember that two negatives = one positive:

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

m = (2)/(1)

m = 2

d).2 is your slope.

Answer 2

Answer:

$\displaystyle =2$

Step-by-step explanation:

The slope formula is ⇒ $\displaystyle\frac{Y_2-Y_1}{X_2-X_1}$

$\displaystyle Y_2=(-1)\\\displaystyle Y_1=(-3)\\\displaystyle X_2=2\\\displaystyle X_1=1$

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

Therefore, the slope is 2, and the correct answer is 2.

Hope this helps!
