Suppose you have designed a new thermometer called the x thermometer. on the x scale the boiling point of water is 129 ? x and the freezing point of water is 13 ? x. part a at what temperature are the readings on the fahrenheit and x thermometers the same?

(x1,y1) (x2,y2)  

(32,15) (212,135)  

y = mx + b  

m=(y2-y1)/(x2-x1)  

m=.66667  

y = .66667*(x) + b  

Plug in #s to test for b value  

15 = .66667*(32) + b  

b = -6.334  

y = mx + b  

y = .6667*(x) + (-6.334)  

F = .6667*(F) + (-6.334)  

F = (.6667*(F) = -6.334  

(F - .6667F) = -6.334  

F(1 - .6667) = -6.334  

F = -19  

ThermX = F @ -19 degrees

Brainliest please!

he would use the colour black

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
