Tx+12y=-3
the equation above is the equation of a line in the xy-plane, and t is a constant. if the slope of the line is -10, what is the value of t?

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.

Hope this is helpful!

I'm sure the answer is a
