WebAs you can see, direct variation is set up in slope intercept form. y = kx is very similar to y = mx. With direct variation, the y-intercept is 0, so you won't have the "+b" portion of slope intercept form. The constant of variation (k) is very … WebA direct variation equation will produce a straight line through the origin (0,0). If k (or the slope) is positive, then the line will rise from left to right, passing through the origin. If k … WebThis is a downward-sloping line. I would say this is a negative. This is a negative linear relationship. But this one looks pretty strong. So, because the dots aren't that far from my line. This one gets a little bit further, but it's not, there's not some dots way out there. And so, most of 'em are pretty close to the line. how to slow down my speaking

WebApr 20, 2015 · 1 Answer. A graph shows direct variation if it goes through the origin, (0,0). The equation is y = kx, where k is a constant, which is apparent when we write the equation as y x = k. In slope-intercept form, the equation would be y = mx +b, where m = k, and b = 0. Lets suppose that k = m = 2. WebWell, a good example is speed and distance. The bigger your speed, the farther you'll go over a given time period. So as one variable goes up, the other goes up too, and that's the idea of direct proportionality. But you can express direct proportionality using equations, and that's an important thing to do in algebra.
