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.

In this unit we nd the gradient of a straight line segment, and the relationships between the gradients of parallel lines and of perpendicular lines.If l1 and l2 are two parallel lines, then the angles 1 and 2 that they make with the x- axis are corresponding angles, and so must be equal. I have been trying to do this problem and I am very confused.

I know the gradient is infinity when any line is parallel to the y-axis, therefore, y inftyInstead, a vertical line (parallel to y-axis) has the equation xa, where a is the x-intercept of the line. This should clarify the (correct) answer Properties of the linear function. Lines parallel to the axes, horizontal and vertical lines.Where, the constant m is called the slope or gradient and the constant c is the y-intercept. TERMINOLOGY.

(a). What is the gradient of the line A ?(c). Lucy decided to investigate more lines. She needed longer axes. Where will the line. y . x 20 cross the y axis? A line that is parallel to the y-axis also has to be vertical.when it come to problems you need to know that undefined also means infinity ehic is equal to 1/0 therefore slope of a line parallel to y-axis is 1/0. Lines parallel to x-axis. Equation of x-axis is. Y 0. Equation of lines which are parallel to x-axis is. Y k. Where k is a constant. Let us check an example. Y 2. Drawing y 2 in graph. Since y 2 for all values of x. Points which satisfy the equation is. X. 0. 1. 2. 1. Y. 2. 2. 2. 2. Plotting points on graph. Example Four - Parallel Lines. The graphs of y 3x (red line) and y 3x 2 (blue line) are shown in the diagram. What do you notice about their gradients (slopes)?The y-intercept is the point at which a graph crosses the y-axis. 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.
