how to circle a equation in a straight line
y= 2x-1
y = x^2+ 2
x –y = 1
x = y + 5
y = – x^2 + 5

In summary, the conversation is discussing the equations for three straight lines and two parabolas, and the concept of "circling" an equation in a straight line is unclear. The equations for straight lines do not contain exponents, while the equations for parabolas do.

You’ve posted the equations for three lines and two parabolas.
I have no idea what you are asking with regard to a circle.
Please translate the original problem to English and post it.

I don't understand what "to circle an equation in a straight line".Abdullah Qureshi said:
means.
This is the equation of a straight line.
This is the equation of a parabola.
This is the equation of a straight line.
This is the equation of a straight line.
This is the equation of a parabola.
There are NO circles.

It possibly means to encircle the equations forming straight lines.

Without making a graph. It can be use as simple way like trigonometryskeeter said:

Straight-line equations, or "linear" equations, graph as straight lines, and have simple variable expressions with no exponents on them. If you see an equation with only x and y, then you're dealing with a straight-line equation. As opposed to, say x² or √x .
The second and the last equations posted above have exponents, so they are not forming straight lines. The rest of them are. You can encircle the rest!

1. What is a circle equation in a straight line?
A circle equation in a straight line is a mathematical representation of a circle on a Cartesian coordinate system. It is in the form of (x-h)^2 + (y-k)^2 = r^2, where (h,k) represents the center of the circle and r represents the radius.
2. How do you graph a circle equation in a straight line?
To graph a circle equation in a straight line, first plot the center point (h,k) on the coordinate plane. Then, use the radius r to plot points on the circle. Connect the points to form a smooth curve, which will be the circle.
3. Can a circle equation in a straight line have a negative radius?
No, a circle equation in a straight line cannot have a negative radius. The radius represents the distance from the center of the circle to any point on the circle, so it must be a positive value.
4. How is a circle equation in a straight line different from a regular circle equation?
A circle equation in a straight line is different from a regular circle equation because it is in the form of (x-h)^2 + (y-k)^2 = r^2, while a regular circle equation is in the form of x^2 + y^2 = r^2. The difference is that a circle equation in a straight line is centered at a point (h,k) instead of the origin (0,0).
5. What is the significance of a circle equation in a straight line in real life?
A circle equation in a straight line has many applications in real life, such as in engineering, architecture, and physics. It is used to represent circular objects or motions, such as wheels, gears, orbits, and circular paths. It also has practical uses in calculating distances, areas, and volumes.
