The intersecting x- and y-axes divide the coordinate plane into four sections. These four sections are called quadrants. Quadrants are named using the Roman numerals I, II, III, and IV beginning with the top right quadrant and moving counter clockwise.
Q. How do I find the x and y intercepts of a parabola?
To find the y-intercept let x = 0 and solve for y. Step 3: Find the x-intercept(s). To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form).

Q. How do you graph linear equations using x and y intercepts?
Since two points determine any line, we can graph lines using the x- and y-intercepts. To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation.
Q. How do you point on a graph?
Follow these simple steps:
- First, find the value for x on the x-axis.
- Next, find the y-value – in this case, y=1100, so find 1100 on the y-axis.
- Your point should be plotted at the intersection of x=0 and y=1100.
- Finally, plot the point on your graph at the appropriate spot.
Q. What are the quadrants on a graph?
The first number in an ordered pair is the x-coordinate. The second number is the y-coordinate. The coordinate axes divide the plane into four regions called quadrants. The quadrants are numbered I, II, III, and IV as shown on the grid below.
Q. Where is the origin on a graph?
Most often, when we use a coordinate graph , each mark on the axis represents one unit, and we place the origin—the point (0,0) —at the center.
Q. What is scale in a graph?
In simple words, a scale is a set of numbers that help to measure or quantify objects. A scale on the graph shows the way the numbers or pictures are used in data. On the y-axis, the numbers are marked at intervals of 5. This indicates that the scale used for the graph is 1 unit is 5 children.
Q. How do you find the point of origin?
An origin is a beginning or starting point, and, in mathematics, the origin can also be thought of as a starting point. The coordinates for every other point are based on how far that point is from the origin. At the origin, both x and y are equal to zero, and the x-axis and the y-axis intersect.
Q. Does a linear line have to go through the origin?
The answer to that is NO, it need not pass through the origin. Consider the relation . This relation is linear, so its graph is a line.
Q. How do I determine if a line pass through the origin?
The slope intercept form is y = mx + b, where b is the y-intercept. In the equation y = 2x – 1, the y-intercept is -1. So, if you have an equation like y = 4x, there is no “b” term. Therefore, the y-intercept is zero, and the line passes through the origin.
Q. What is the slope of a line passing through the origin?
If the line passes through the origin, then you know that (0,0) is on the line. If the line is perpendicular to y=2x+3 then we know the line has slope m=−0.5.
Q. Does the best straight line pass through the origin?
If one variable is directly proportional to another variable, then a graph of these two variables will be a straight line passing through the origin of the axes. Notice that the best-fit line does not necessarily pass through any of the data points.
