Answer:
c = –13
Step-by-step explanation:
by property of tangent line, equation
x² – x – 12 = x + c
x² – 2x – 12 – c = 0
has only one solution, which mean
– 12 – c = 1
c = –13
Y=2x-3 rise over run and then the y intercept
Shouldn't this be in the language section? But okay. I would say the simple subject would be "plane"
