Water boils at 100LaTeX: ^\circ∘ Celsius or 212LaTeX: ^\circ∘ Fahrenheit. Water freezes at 0LaTeX: ^\circ∘ Celsius or 32LaTeX: ^\circ∘ Fahrenheit. If the weather forecaster says it will be 30LaTeX: ^\circ∘ Celsius today, write and solve a linear equation to find what Fahrenheit temperature this is.

Step-by-step explanation:

Represent Celsius with C and Fahrenheit with F.

So, we have:

Solving (a): Represent as a linear equation

First, we calculate the slope:

This gives:

The linear equation is then calculated using:

Where

Make F the subject

Solving (b): The value of F when C = 30

Substitute 30 for C in

answer: x
