how do you find the equation of the tangent line at the given point on each curve?

x2+ y2=25 , (-3,4)


Expert Answer

Step 1

To determine the equation of the tangent line, the slope of the curve at the given point is to be determined.


Slope of the curve is given by m = dy/dx


Applying derivative to the equation of the curve with respect to x:

Hence, the slope of the curve at (-3,4) is given by:

Step 2

The tangent line passes through the given point.

Equation of a line with slope m and passing through the point (x1,y1) is given by y - y1 = m(xx1)

Plugging the values,

Hence, the equation of the tangent line ...
