What is the y-intercept of the graph of a direct variation equation?
Graphs of direct variation pass through the origin so the y-intercept would be 0.
Is the equation Y MX B a constant of variation?
No, it is a linear equation which does not pass through the origin unless B = 0. If B = 0 then Y and X could be said to vary in direct proportion and M would be the constant of variation, not the whole equation.
Does y vary directly with x in the equation y equals 5x?
Yes, this is an example of direct variation.A:This is a direct variation because both are in the numerator of a fraction and on opposite sides of the = sign. If they are both on the same side of the equals sign, then one would have to be in the numerator and the other in the denominator for them to be a direct variation.
Is -3x -35y equals 14 a direct variation?
no. direct variation implies that you can simplify the problem into several forma which are equivalent to y/x = k in which k is called the constant of variation. one of these equivalent forms would by y = kx + 0 (slope intercept form) in which the y intercept must be 0 rearranging your equation gives a y- intecept of -14/35 which reduces to -2/5 since this is not zero. this is not direct variation.
What is direct variation and how would solve direct variations?
k=0.3 and x=65
