Question

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

Answer 1

`\displaystyle 2`

Explanation:

Slope formula: ⇒
`\displaystyle (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 (5-1)/(3-1)=(4)/(2)=2`

Therefore the slope is 2.

2 is the correct answer.

Hope this helps!

Answer 2

m = 2

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
