Example Question #1501 : Intermediate Geometry
What is the slope of the tangent line to the graph of 
To find the slope of the tangent line, first we must take the derivative of 
Example Question #11 : Tangent Lines
Suppose the equation of a line is 
Rewrite 
The slope of the tangent line is 
Example Question #221 : Coordinate Geometry
Suppose a function 
Write the formula for slope-intercept form.
The slope of 
Example Question #1 : How To Find X Or Y Intercept
Given the line 
The intercepts cross an axis.
For the 
For the 
So the sum of the intercepts is 
Example Question #2 : How To Find X Or Y Intercept
What are the 
To find the intercepts of a line, we must set the 
Example Question #1 : How To Find X Or Y Intercept
What is the 
The 
Example Question #3 : How To Find X Or Y Intercept
Which of the following statements regarding the x and y intercepts of the equation 
The x-intercept is greater than the y-intercept.
The graph does not cross the y-axis.
The y-intercept is greater than the x-intercept.
The x and y intercepts are equal.
The graph does not cross the x-axis.
The y-intercept is greater than the x-intercept.
To find the x-intercept, we simply plug 
Example Question #2 : How To Find X Or Y Intercept
Find the 
DNE
To find the x-intercept, set y equal to 0.
Now solve for x by dividing by 3 on both sides.
This reduces to,
Example Question #3 : How To Find X Or Y Intercept
Find the 
To find the y-intercept, set x equal to 0.
Now solve for y.
Example Question #3 : How To Find X Or Y Intercept
Which is the x-intercept for the line 
The x-intercept of a line is the x-value where the line hits the x-axis. This occurs when y is 0. To determine the x-value, plug in 0 for y in the original equation, then solve for x:
