THANK YOU ,AND I HAVE ANOTHER QUESTION FOR AN INPUT VALUE (X VALUE) OF 10, WHAT IS THE OUTPUT (Y) VALUE

amistre64 · Answer

im assuming we are working with the line that is defined between these 2 points;

y = (9/5)x + 32 ; when x = 10

y = 9(10/5) + 32

y = 9(2) + 32

y = 18 + 32

y = 50 ; when x = 10
