# Quick Answer: What Is The Y-Intercept Of Y =- 3?

## What is the slope and y-intercept of y =- 3x 4?

2 Answers By Expert Tutors The equation of the line in question is: y = 3x – 4 , which is in slope-intercept form.

Note that the general form of the slope-intercept equation is: y = mx + b , where m is the slope of the line (rise/run) and b is the y-intercept of the line (the point where x=0)..

## What is the Y intercept of the line y 2x 8?

The y -intercept is (0,8) .

## How do you calculate the Y intercept?

You can describe a straight line with the formula y = mx + b, where m is the slope and b is the y-intercept. Now that we know the slope m and a point (x,y), we can use this equation to solve for b, the y-intercept. Fit the slope and point into the equation.

## What is the Y intercept of y =- 3 7x?

The slope is 37 and intercept on y axis is 0 .

## What is the Y intercept of Y 3 4x 2?

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

## What is the slope of y =- 3?

y=3 would be nothing more than a horizontal line through y=3. So the rise is always 0 (it never goes up or down) and the run is always the distance from zero to any point on the line. In other words, the slope would be 0/the change in x, which is always 0.

## What is the Y intercept of y =- 2?

Explanation: y=−2 is a flat line crossing the point at (0,−2) therefore the gradient is zero and the the y intercept is -2.

## Which is the Y intercept in an equation?

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

## What is the slope of y =- 3x 4?

Using the slope-intercept form, the slope is −3 .

## Is y 3x 4 a linear equation?

y=3x+4 is a linear equation as all components are linear in terms of x (i.e. the only exponents of x are 0 or 1).

## What is the Y intercept of y =- 4?

1 Expert Answer The line crosses the y axis (the y-intercept, where x=0) at y=4. The point (0,4). Since it is a horizontal line, y = 4 no matter what value x has. y = (2/3)x + 0 has a y-intercept of (0,0) and rises 2 values of y for every 3 value increases in x.

## What is the Y-intercept of Y 3 4x?

Using the slope-intercept form, the y-intercept is 0 .

## What is the slope of the line y 3x 7?

-31 Expert Answer In the slope-intercept form of linear equation (y=mx+b) the slope is the number next to the x, here represented with the letter m. In your equation, y =-3x+7, the m is replaced by -3, so the slope here is -3.

## What is the slope of y =- 4?

The slope is 0 and the y-intercept is -4.
