Ok here is the Problem.
Weather Temperature. The National Oceanic and Atmospheric ADministration (NO) has an online cconversion chart that relates degrees Fahrenheit to degrees Celsius. 77deg F is equevalent to 25deg C and 68deg F is equivalent to 20deg C. Assuming relationship is linear, write the equation relating degrees Celsius C to degrees Fahrenheit F. What temperature is the same in both degress Celsius and degress Fahrenheit?
Here steps I did:
77deg F = 25deg C
68deg F = 20deg C
Let x = Fahrenheit and y = Celsius
Linear Equation: y=mx + b or C = mF + b
Two Points of this Equation is (77,25), (68,20)
Solving the equation:
Calculate the change of rate:
Subtitute the slope into the linear equation.
I use either point to satisfy the equation. I use (77,25)
Let x = 77
I don't know if i'm this right. I still haven't answer the other question: What temperature are both the same degrees.
