SOLUTION: Let g be a linear function. If g(1)=3 and g(-4)=c, find the value of the constant c such that the line will have a slope equal to -1. Also, could you solve this one? 12x-45=-{48-

Question 56132: Let g be a linear function. If g(1)=3 and g(-4)=c, find the value of the constant c such that the line will have a slope equal to -1.
Also, could you solve this one?

Let g be a linear function. If g(1)=3 and g(-4)=c, find the value of the constant c such that the line will have a slope equal to -1.
:
The formula for the slope is:

:
Check:

Looks good.

For the second one.
12x-45=-{48-12x+3}
12x-45=-{51-12x}
12x-45=-51+12x
-12x+12x-45=51+12x-12x
-45=51
You ran out of variables and the sides aren't =, therefore there is no solution.
Happy Calculating!!!
