How do you find the intersection of a line with the Y axis?

The y-intercept is the point at which the graph crosses the y-axis. To find the x-intercept of a line, substitute 0 for y into the equation and solve for x. To find the y-intercept of a line, substitute 0 for x into the equation and solve for y. You can use the intercepts to graph the line.

How do you tell if an equation is parallel/perpendicular or neither?

We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.

How do you prove lines are perpendicular?

Perpendicular lines intersect at right angles to one another. To figure out if two equations are perpendicular, take a look at their slopes. The slopes of perpendicular lines are opposite reciprocals of each other.

What is quadrant or axis?

Quadrant is the region enclosed by the intersection of the X-axis and the Y-axis. On the cartesian plane when the two axes, X-axis and Y-axis, intersect with each other at 90º there are four regions formed around it, and those regions are called quadrants.

On which axis does the point 0 2 lie?

y-axis
(i) Point (0, –2) lies on y-axis.

How do you know if an equation is perpendicular?

Do perpendicular lines have to intersect?

When two lines are perpendicular, the slope of one is the negative reciprocal of the other. Note too that the lines to do not have to intersect to be perpendicular. In Fig 1, the two lines are perpendicular to each other even though they do not touch.

How do you work out parallel lines?

How do you know if two lines are parallel in a triangle?

Determining if Two Lines are Parallel Use the Triangle Proportionality Converse. If the ratios are equal, then the lines are parallel.
