Micah's rain gauge showed 9 1/2 centimeters of rain fell last month this month , The rain guage measured 10 3/10 centimeters . How many centimeters of rainfall this month

4/5 centimeters

Step-by-step explanation:

From the question, we are informed that Micah's rain gauge showed 9 1/2 centimeters of rain fell last month and that this month, the rain guage measured 10 3/10 centimeters .

The centimeters of rainfall that fell this month will be:

= 10 3/10 - 9 1/2

= 10 3/10 - 9 5/10

= 8/10

= 4/5 centimeters

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
