Question

Find the slope between (1,1) and (3,5).

Answer 1

Answer:

$\displaystyle 2$

Step-by-step explanation:

Slope formula: ⇒ $\displaystyle \frac{Y_2-Y_1}{X_2-X_1}$

$\displaystyle Y_2=5\\\displaystyle Y_1=1\\\displaystyle X_2=3 \\\displaystyle X_1=1$

$\displaystyle \frac{5-1}{3-1}=\frac{4}{2}=2$

Therefore the slope is 2.

2 is the correct answer.

Hope this helps!

Answer 2

Answer:

m = 2

Step-by-step explanation:

As we move from (1, 1) to (3, 5), x increases by 2 and y increases by 4.

Thus, the slope of the line connecting these two points is

m = rise / run = 4 / 2 = 2.  m = 2
