Slope = (-14-1)/(7-1) = -15/6
y = mx + c
y = -15/6 x + c
at (1,1)
1 =-15/6(1) + c
c = 1 + 15/6 = 21/6
y = -15/6 x + 21/6 or
6y = -15x + 21
You would square 3968 and subtract 1.
The answer is 6. 8-6(6) = -28.
To start, you need to subtract 4x from both sides, that way, x is one one sid of the equation.
