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

## 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?
