Slope of tangent line = dy/dx = 2x+3
k is y_intercept of tangent line

2x+3 = -1
x = -2
y = (-2)^2+3(-2)+1 = -1

tangent line passes through point (-2,-1)

k = x+y

k = -2 -1

k = -3

How do I solve this??
pshichka [43]
Well, first you should make both sides of the equation to the power of 2. 
So, you'll have 7X = 1225, and then X is 175 :)

Have a wonderful day!
