    two-variable equations

    Celsius temperature readings can be converted to Fahrenheit readings using the formula F= 9/5 C +32. What is the Fahrenheit temperature that
    corresponds to each of the following Celsius temperatures: -10, 0, 15, 100?

    My answer for (-10, is F =14) am I right? I am not sure on the rest of the Celsius temperatures.

    This is how I came about of the answer for Celcius temperature of -10

    F= 9/5 (-10) = 32

    F= -18 +32

    F = 14

    Exactly. Now do the same for the rest. I'll do 15 C:
    F = (9/5)(15) + 32

    F = 27 + 32

    F = 59
