Question

On a linear X temperature scale, water freezes at -125.00X and boils at 375.00 X.

On a linear Y temperature scale, water freezes at -70.000 Y and boils at -30.000

Y. A temperature of 50.000 Y corresponds to what temperature on the X scale?

Answer 1

$∆X=500,$

$∆Y=40000,$

$Y_0=-50000,$

$X_0=125.$
