PLZ HELP BASIC c ALGEBRA BRAINLIEST TO QUICKEST ANSWER
Biologists have found that the number of chips some crickets make per minute are related to temperature. When crickets chirp 124 times a minute it is about 68 degrees Fahrenheit. When they chirp 172 times a minute, it is about 80 degrees Fahrenheit.

Write an equation in Slope Intercept, Standard, or Point Slope form that represents the situation.

Respuesta :

The standard linear equation is:
mx + b = y

So here's what we know:
68x + b = 124
80x + b = 172

If we invert the first equation, we can get rid of b and thus isolate x:
80x + b = 172
-68x - b = -124
12x = 48
x = 12

Now that we have x, we can solve for b:
68 * 4 + b = 124
272 + b = 124
b = -148

Let's check our answer:
80*4 - 148 = 172
320 - 148 = 172
172 = 172

So our final equation is:
4 * Temp - 148 = chirps
