Answer:

7x - 5 = 11

Step-by-step explanation:

To solve for x, substitute y = -5 into the equation 7x + y = 11.

This becomes 7x + (-5) = 11 or 7x - 5 = 11.

What is the slope of the tangent line through (3,2) and (x,y) for x=-2 and y=x3
Allushta [10]
First you must derive the equation to find the slope:
  y = x ^ 3
 y '= 3x ^ 2
 Then, for x = -2 we have the slope is:
 y '(- 2) = 3 (-2) ^ 2 = 12
 Then the equation of the line with slope equal to 12 and passing through point (3,2) is:
 y = 12 (x-3) +2
