What does the graph of the equation 2x-3y equals 6 look like?
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
How do you graph the equation x plus 3 equals 0?
Move 3 over the right side of the equation so the equation would be x = -3. The graph of this would be a verticle line at x= -3
Which of the lines below is the graph of the equation y equals x plus 1?
answer is 1
What is the equation of the line tangent to the graph y equals sin 2x?
That line is [ y = 2 cos(2x) ].
Find the equation of the line tangent to the graph of y equals cos2x at x equals pi divided by 4?
0.5
An equation of the line tangent to the graph of y equals x3 plus 3x2 plus 2 at its point of inflection is?
(a) y = -3x + 1
Derivative as the Slope of a Tangent?
Yes, the derivative of an equation is the slope of a line tangent to the graph.
What is the graph of y equals x cubed called?
A cubic function.
Determine the point at which the graph of the function has a horizontal tangent line for the equation?
For the equation (9x^2)/(x^2+4)
Graph the equation -5y equals -40?
35
How do you get the tangent line without the graph?
The answer will depend on the context. If the curve in question is a differentiable function then the gradient of the tangent is given by the derivative of the function. The gradient of the tangent at a given point can be evaluated by substituting the coordinate of the point and the equation of the tangent, though that point, is then given by the point-slope equation.
What would you do if the equation had x squared or x cubed in the polynomial equation?
It depends on what you wanted to do - graph it, solve it, factorise it, etc.
What is a tangent line?
Tangent line is a graph. This graph is to gather data.
What does the graph of the equation 2x-3y equals 6 look like?
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
What is the slope of the equation y equals -x?
The equation has no slope. The graph of the equation is a straight line with a slope of -1 .
