What are the intercepts of 2x y =- 4?

The x -intercept is (−2,0) and the y -intercept is (0,4) .

How do you find the intercepts of an equation?

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. For example, lets find the intercepts of the equation y = 3 x − 1 \displaystyle y=3x – 1 y=3x−1. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

What are the intercepts of y x 2?

The equation y=x+2 , which is the slope-intercept form for a linear equation y=mx+b , where m is the slope, and b is the y-intercept. Therefore the y-intercept for y=x+2 is 2 . The x-intercept is the value of x when y=0 .

What is the slope and y-intercept of 2x y =- 4?

Using the slope-intercept form, the slope is 2 .

What is the slope-intercept form of 2x y 4?

Algebra Examples The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Rewrite in slope-intercept form. Subtract 2x 2 x from both sides of the equation. Multiply each term in −y=4−2x – y = 4 – 2 x by −1 – 1 .

How do you find the intercepts of two lines?

What is the slope and y-intercept of yx 2?

The slope is 1 and the y-intercept is simply 2. 2nd methode: To find the x or y intercepts in any form of the equation of the line, simply set y or x to zero and solve for x or y respectively.

What is the solution to the equation 2x y 4?

The answer is y=−2x+4 .

What is the slope of Y 4 − 2x?

−2
Here, 4 is b and −2 is m . Therefore, the slope is −2 .

What is Y 4 in slope-intercept form?

The line y=4 is really y=(0)x + 4. The slope is 0, so it is a horizontal line (it doesn’t rise or fall as x increases). The line crosses the y axis (the y-intercept, where x=0) at y=4. The point (0,4).

How do you find y intercept from an equation?

To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve for y.

How do you calculate intercept?

The y-intercept is the point at which a linear equation crosses the y-axis on the x=0 plot point. The equation to determine both the slope and the y-intercept of a line is y=mx+b. This calculation may be calculated by hand or by using a software program capable of solving complex mathematics.

How do you find the X and y intercept?

– 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 the formula for finding x – intercept?

To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’. To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’. In this tutorial, you’ll see how to find the x-intercept and the y-intercept for a given linear equation.
