Given:
The equation of line is
To find:
The x and y-intercept of the given line.
Solution:
We have,
Putting x=0, we get
Add 6 on both sides.
Divide both sides by 4.
So, the y-intercept is .
Putting y=0 in given equation, we get
Add 5 on both sides.
Divide both sides by 7.
So, the x-intercept is .
The tangent to at the point (0, 5) has a slope equal to the derivative evaluated at
.
This tangent passes through the point (0, 5), so its equation is
The normal line passes through the same point, but is perpendicular to the tangent line, so its slope is the negative reciprocal of the slope of the tangent. So the equation for the normal line is
