Each worksheet itself is scaffolded three different ways to allow for optimum . If you square both sides you will get. Find the equation of the line through two given points, or through one point with a given gradient. 3 The equation x = ky (where k is a real number) represents a line parallel to Y-axis i.e . So you can get the mass oscillating if you desire from the gradient of the graph you plotted. The general equation of a linear function is ax + by + c = 0. e.g.
Their shape is a straight line, and the gradient is constant along the line. The final equation is. Draw a straight line through all the plotted coordinates across the whole plotting area.
