On a graph, parallel lines have the same gradient. For example, y 2x 3 and y 2x - 4 are parallel because they both have a gradient of 2.In the question we are told that the line passes through the point (0, 2). This means that the line crosses the y axis at 2. The gradient of a line is determined by the ratio of vertical change to horizontal change.Two lines that run parallel to each other are always the same distance apart and have equal gradients. Slope is nothing but the dis ambiguity or gradient or pitch of the curve or line. And is defined as the rate at which line is rising or inclined to a particular axis.Whenever a line is parallel to Y axis then slope is undefined.

If its parallel to the y-axis, then its of the form xa, so it has no gradient (or it has an infinite gradient, since youre basically considering gradienttan(pi/2)). Moreover, if a curve has a tangent that is parallel to the y -axis, then it cant be a graph of a function. (Think "horizontal line test.") Example 1. Find the gradient of the line adjoining A (2, 4) and B (5, 9). Decide which point will represent (x2, y2) and which will represent (x1, y1 ) They must workC (-1, 1) It is unimportant where the x and y axes are! We can see from this that BC is PARALLEL to AD And AB is PARALLEL to DC. cyolba. It has a gradient of inifinity (which doesnt exist) of course!The x axis has gradient 0. The y axis has gradient 1/0 (as above.) The product of the gradients of 2 perpendicular lines is -1.
