## What is the Y intercept in the equation y =- 2x 5?

In this equation, y = 2x – 5, it is already in that form and so the cumber in front of the x is the slope (2) and the constant number is the y-intercept (-5) – it’s negative because of the minus sign in front of the number. So, the slope is 2 and the y-intercept is -5.

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

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

## What is the equation of Y 4x 3?

y = 4x + 3 is in what is called “slope-intercept” form or “y=mx+b” form which is the easiest form for graphing. The “3” is called the “y-intercept” and is where the line crosses the y axis. So, go to the “origin” (0,0) and go up three on the vertical line.

## What is the Y-intercept in the 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 Y intercept when given two points?

Steps

- Calculate the slope from 2 points. For Example, Two points are (3, 5) and (6, 11)
- Substitute the slope(m) in the slope-intercept form of the equation.
- Substitute either point into the equation. You can use either (3,5) or(6,11).
- Solve for b, which is the y-intercept of the line.
- Substitute b, into the equation.

## Which function has the greatest Y intercept?

Answer: The function f(x) has the greatest y-intercept.

## Is the Y intercept always positive?

It’s called the “y intercept” and it’s the y value of the point where the line intersects the y- axis. For this line, the y-intercept is “negative 1.” You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

## Which function has the smallest minimum y value 2 points?

The square function has minimum 0, so g(x) has minimum 0-1=-1. h(x) has minimum -6 when x=1, so it has the smallest minimum.

## Which function has the smaller y intercept?

Answer: C. The y-intercept of the graph is 4 so it is the smallest.

## What happens if there is no Y intercept?

If a line has no y-intercept, that means it never intersects the y-axis, so it must be parallel to the y-axis. This means it is a vertical line, such as . This slope of this line is zero. A real-life situation of a line that has no y-intercept is the equation of a vertical wall.

## Which is Y intercept of the graphed function?

The y -intercept of a graph is the point where the graph crosses the y -axis. (Because a function must pass the vertical line test , a function can have at most one y -intercept . ) The y -intercept is often referred to with just the y -value.

## Why is the Y intercept important?

Linear equation intercepts are important points to be able to understand and decipher in applications of linear equations problems and can also be used when graphing lines. The y-intercept is used when writing an equation in slope-intercept form.

## Which function has the smallest y-value?

The function f(x) has smallest minimum y-value.

## Which function has the smallest minimum?

f(x) has the smallest minimum. The largest sin(x) can get is 1. This applies to sin(2x-pi) as well. So f(x) is as small as -5*(1)+2 = -5+2 = -3.

## What is the smallest minimum y-value?

The function g(x) has smallest minimum y-value.

## Which function has the largest maximum?

Therefore, the function f(x) has largest maximum.

## What quadratic function has the largest maximum over the set of real numbers?

Which quadratic function has the largest maximum over the set of real numbers? Choice (3) is in vertex form. It’s maximum point occurs at (5, 5)….
