## How do you calculate X or Y?

College Algebra

- 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.
- To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
- 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.
