Answer:
y=3x-2
Step-by-step explanation:
The formula for slope is y=mx=b
You can find the slope by finding two points that lie on the line (1,1) & (0,-2)
The formula for slope is 
You plug the values in and you get 
Simplify and you get 3
The slope is 3
The y-intercept (b) is -2
Answer:

Step-by-step explanation:
Let
x----> the temperature in degrees Fahrenheit
y ---->insect chirping rate in times per minute
we have the ordered pairs
(82,61) and (91,124)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
substitute the values
step 2
Find the equation of the line
we know that
The equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have
---> the units are chirps per minute/degree F
take the point (82,61)
substitute and solve for b



substitute

Perimeter= 2 ( length + width)
2×(12+6)
2×18
=36
The answer is -1 because I don’t really know the real answer
