Question

Tx+12y=-3

Answer 1

In form
ax+by=c
slope=-a/b

a=T
b=12
slopt=-10
-10=-T/12
multiply both sides by 12
-120=-T
mulitply -1
120=t


T=120

Answer 2

First, you need to write this equation in the y = ax + b structure.
To do this, you need to isolate the y on one side.

The 'a' in the formula is your slope, so replace it with (-10), and solve the equation. You'll get the answer.
