y = - 3x
which equation has a slope of -1/2 and a graph that passes through (-3,4)?
For a direct variation, y=kx where k is the constant of variation if x =0 then y=0 and the graph of y=kx passes through the origin. -Indiana Prentice Hall Algebra 2 Text Book.
goes through the origin, up and to the right
Points: (0, -2) and (6, 0) Slope: 1/3 Equation of line: 3y = x-6
If y is equal to 2x, the graph would be a straight line going through the origin. The line would go up and to the right, and the angle at the origin has a tangent equal to 2. This angle is between 63 and 64 degrees.
which equation has a slope of -1/2 and a graph that passes through (-3,4)?
Slope = 1Y-intercept = 0Y = X
The answer depends on how the information is presented. If in the form of a graph, it must be a straight line through the origin. If in the form of an equation, it must be of the form y = cx.
Inverse variation does not pass through the origin, however direct variation always passes through the origin.
Yes Ax + By = C As the line passes through the origin then x = 0 when y = 0. Substituting gives, 0 + 0 = C therefore C = 0.
No.A directly proportional graph has an equation of the form y = mx. It always passes through the origin.A linear graph will have an equation in the from y = mx + c. This has a y-intercept at (0, c). It doesn't pass through the origin unless c = 0. The directly proportional graph is a special case of a linear graph.
For a direct variation, y=kx where k is the constant of variation if x =0 then y=0 and the graph of y=kx passes through the origin. -Indiana Prentice Hall Algebra 2 Text Book.
y = -4x The y-intercept is zero. That is, the graph passes through the origin.
If the function is a straight line equation that passes through the graph once, then that's a function, anything on a graph is a relation!

-- Take the equation -- Set either 'x' or 'y' equal to zero -- Solve the resulting equation for the remaining variable -- If the remaining variable is then also zero, then the origin is on the graph of the function If the graph is a straight line ('x' and 'y' appear in the equation only to the 1st power), then the equation has to be in the form of a simple ratio ... like (y = Kx) or (x = Ky) or (xy = K) or (x/y = K) ... in order to go through the origin.
-- Put a dot at the point where (x=1, y=5). -- Move your ruler so that the dot and the origin are both on the edge of the ruler. -- Draw a line along as much of the ruler as you want to. That line is the graph of y = 5x, which is the equation of the line you're describing.
