Find the equation of the tangent line to the graph

How do you find the equation of a line?

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

How do you find the tangent equation?

In order to find the equation of a tangent, we:Differentiate the equation of the curve.Substitute the value into the differentiated equation to find the gradient.Substitute the value into the original equation of the curve to find the y-coordinate.Substitute your point on the line and the gradient into.

How do I find the slope of the line?

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

Is the slope of a tangent line the derivative?

The derivative of a function gives us the slope of the line tangent to the function at any point on the graph. This can be used to find the equation of that tangent line.

What’s the tangent?

more In a right angled triangle, the tangent of an angle is: The length of the side opposite the angle divided by the length of the adjacent side. The abbreviation is tan.

How do you write an equation for a line on a graph?

The slope-intercept form of a linear equation is written as y = mx + b, where m is the slope and b is the value of y at the y-intercept, which can be written as (0, b). When you know the slope and the y-intercept of a line you can use the slope-intercept form to immediately write the equation of that line.

How do you graph a line from an equation?

To graph a linear equation, we can use the slope and y-intercept.Locate the y-intercept on the graph and plot the point.From this point, use the slope to find a second point and plot it.Draw the line that connects the two points.
