How do you calculate X or Y?

How do you calculate X or Y?

College Algebra

1. To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.
2. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
3. To find the y-intercept, set x = 0 \displaystyle x=0 x=0.

What is X and Y in?

The x-axis and y-axis are axes in the Cartesian coordinate system. The x-axis is usually the horizontal axis, while the y-axis is the vertical axis. They are represented by two number lines that intersect perpendicularly at the origin, located at (0, 0), as shown in the figure below.

How do you plot XY?

Cartesian points are written as xy pairs in parentheses, like so: (x, y). To graph a point, first locate its position on the x-axis, then find its location on the y-axis, and finally plot where these meet.

What is the slope of a line whose equation is y 12x 7 *?

-12
In the equation y=−12x+7 y = − 12 x + 7 the slope is -12, and the y-intercept is 7.

What is x + -1y = 25?

Simplifying x + -1y = 25 Solving x + -1y = 25 Solving for variable ‘x’. Move all terms containing x to the left, all other terms to the right. Add ‘y’ to each side of the equation. x + -1y + y = 25 + y Combine like terms: -1y + y = 0 x + 0 = 25 + y x = 25 + y Simplifying x = 25 + y

What is the x axis and y axis in math?

X and y axis The x-axis and y-axis are axes in the Cartesian coordinate system. Together, they form a coordinate plane. The x-axis is usually the horizontal axis, while the y-axis is the vertical axis. They are represented by two number lines that intersect perpendicularly at the origin, located at (0, 0), as shown in the figure below.

How to find the X- and y-intercept of a graph?

Given an equation, plugging in x = 0 will yield the y-intercept and plugging in y = 0 will yield the x-intercept. Find the coordinates of the x- and y-intercepts of the graph of y = 2x + 6.

How do you add x and Y to get 2x=30?

Eliminating ‘y’ from equations i and ii we get 2x = 30. So x = 15 and hence y = 10. X+Y=25,X-Y=5, ADD BOTH the equations then u get 2X=30. From jere we get X=15.
