Answer:
-10
Step-by-step explanation:
First, we need to find the slope, defined by m, using the equation
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
First, we must choose points. I will choose (2, 165) as point 1 and (1, 175) as point two, so:
x1= 1
y1= 165
x2= 2
y2= 175
Now, let's plug it in.
[tex]m = \frac{175 - 165}{1 - 2} = \frac{10}{ - 1} = - 10[/tex]
For the next one, we follow the same process.
Point 1: (3, 165)
Point 2: (2, 175)
[tex]m = \frac{175 - 165}{2 - 3} = \frac{10}{ - 1} = - 10[/tex]
