    Tangent
In summary, the equation of the tangent line for y = -7x + 5 at the point (1,1) is y = -7x + 5. The slope of the tangent line is the same as the slope of the original line, which is -7. The point (1,1) is the point of tangency, where the tangent line touches the original line. The equation of the tangent line can be used to find other points along the line, but they may not be points of tangency and the slope may not be the same as the original line. The equation of the tangent line is a representation of the slope and point of tangency of the original line, sharing the same slope but passing through

Determine the equation 1 the tangent to the given function, at the given point.

y = (3x^-2 - 2x^3) , @ (1,1)

pretty sure you need to take the derivative of that. The dy/dx (derivative) you get out of that after plugging everything in is your slope of the tangent. Then just solve for your y-intercept.

*edit* The other questions you just posted are really the same idea as this.

Related to Equation of Tangent: y = -7x + 5 @ (1,1)

1. What is the equation of the tangent line for y = -7x + 5 at the point (1,1)?

The equation of the tangent line for y = -7x + 5 at the point (1,1) is y = -7x + 5.

2. How do I find the slope of the tangent line for y = -7x + 5 at the point (1,1)?

The slope of the tangent line for y = -7x + 5 at the point (1,1) is the same as the slope of the original line, which is -7.

3. What is the significance of the point (1,1) on the tangent line for y = -7x + 5?

The point (1,1) is the point of tangency, where the tangent line touches the original line y = -7x + 5. It is also the point where the slope of the tangent line is equal to the slope of the original line.

4. Can I use the equation of the tangent line to find other points along the line?

Yes, you can use the equation of the tangent line to find other points along the line by plugging in different values for x. However, these points will not necessarily be points of tangency and the slope of the line may not be the same as the slope of the original line.

5. How does the equation of the tangent line for y = -7x + 5 at the point (1,1) relate to the graph of the original line?

The equation of the tangent line for y = -7x + 5 at the point (1,1) is a representation of the slope and point of tangency of the original line. It is a linear equation that shares the same slope as the original line, but passes through the point of tangency (1,1) instead of the y-intercept (0,5).
