What’s the slope of the line that passes through 5,10 and 7,12
Marrrta [24]

Slope of the line passes through (5,10) and (7,12) is 1.

Step-by-step explanation:

Given,

The two points are (5,10) and (7,12).

To find the slope passing through the given points.

Formula

The slope of the line passing through (x_{1} ,y_{1}) and (x_{2} ,y_{2}) is \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

Now, putting x_{1} =5,y_{1}=10, x_{2}=7, y_{2} =12 we get,

Slope = \frac{12-10}{7-5} = \frac{2}{2} = 1

Hence,

Slope of the line passes through (5,10) and (7,12) is 1.

Average rate of change [1,3] = (15.882 - 11.38)/(3-1) = 4.502 /2 = 2.251


average rate of change [-4,-2] = (0.0971- 0.0018)/(-2+4) = 0.0953 /2 = 0.04765

average rate of change [1,3]  / average rate of change [-4,-2] 
= 2.251 / 0.04765
= 47.24

answer
47.24
