Your answer is C.The relation passed the vertical line test.
1.
3 x 4 = 12
3 + 4 = 12
The two integers a and b are : 3 and 4
2.
-4 x 1 = -4
-4 + 1 = -3
The two integers a and b are : -4 and 1
3.
-3 x -3 = 9
-3 + -3 = -6
The two integers a and b are : -3 and -3
There you go! I really hope this helped, if there's anything just let me know! :)
For part A: the constant is 83.50. the variable would be c and w. and the coefficient would be 10c or 15w.
part B: so 10(4)+15(15)+83.50 -----> 10x4= 40------> 40+15(15)+83.50---->15x15=225
40+225+83.50=348.50
part C The coefficient would change because a constant is always constant, a variable is just a letter standing in for a number which would make the coefficient the one that changes for $10 to $20.
hope that help!
