# What is the y-intercept of the function f x 2 9x 1 3?

## What is the y-intercept of the function f x 2 9x 1 3?

Summary: The y-intercept of the function f(x) = -2/9x + 1/3 is 1/3.

What is the slope of the line represented by the equation y equals 2 3 5x?

Algebra Examples Using the slope-intercept form, the slope is −5 .

What is the slope of the line represented by the equation y =- 1 2x?

-1/2
Summary: The slope of the line represented by the equation y = -1/2x + 1/4 is -1/2.

### What is the y-intercept of the equation y?

When the equation of a line is written in slope-intercept form (y=mx+b), the y-intercept is the constant, which is represented by the variable b. For example, in the linear equation y=4x−5, the y-intercept is −5.

How do you find the y intercept of a function?

y- Intercept: A y -intercept of a function is the point where the graph of the function touches or crosses the y -axis. The y -intercept always has an x -coordinate of 0, so it can be found by substituting x = 0 into the function.

What is the formula for finding y intercept?

y-intercept = b = B/C. Alternatively, To find the x-intercept, substitute y = 0 and solve for x. i.e. Ax + B(0) = C. Ax = C. x = C/A. To find the y-intercept, substitute x =0 and solve for y. i.e. A(0) + By = C. By = C. y = C/B. Go through the example given below to understand this concept in a better way. Example: Let us assume the straight-line equation 5x +2y =10

#### How to solve for the y intercept?

m represents the slope of a line

• b represents the y-intercept of a line
• x and y represent the ordered pairs throughout a line
• How do you calculate 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.
