Using the slope-intercept form, the slope is 2 .
How do u find the y-intercept?
The standard form of a quadratic equation is written as y=ax2+bx+c, where x and y are variables and a, b, and c are known constants. To find the y-intercept from a quadratic equation, substitute 0 as the value for x and solve. The y-intercept is always equal to the value of c in the equation.

How do I find slope?
Using the Slope Equation Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
How do you find the slope formula?
Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

What are the 3 slope formulas?
There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.
Answer
This is because your questions is in an y=mx+b form therefore b is the y-intercept and in this equation -3 would be b therefore that the is the y-intercept

this equation when plugged into a graphing calculator gives one y-intercept value .3 repeating
What is the y -intercept of an equation?
When the equation of a line is written in slope-intercept form ( y = m x + b), the y -intercept is the constant, which is represented by the variable b. For example, in the linear equation y = 4 x − 5, the y -intercept is − 5.
How to find the y intercept of a line?
If you already have the equation of the line, solve algebraically to find the y-intercept. Since the y-intercept always has a corresponding x-value of 0, replace x with 0 in the equation and solve.
Where is the y -intercept on a graph?
The y -intercept is the point where the graph of a line crosses the y -axis. In the coordinate plane shown, the y -intercept is 4 because the graph passes through 4 on the y -axis.
How do I find slope and y -intercept?
The corresponding x -coordinate is always 0. The slope is found by calculating rise over run. This is done by finding the difference in the y -coordinates and x -coordinates and dividing these differences.
What does the y -intercept mean in real life?
The y -intercept is the y -value that corresponds to x when x = 0. In real life, this often refers to the starting point when something is being measured.
What is the slope of a linear equation?
When a linear equation is written in slope-intercept form ( y = m x + b), the slope is represented by the variable m. It is the coefficient to x in the equation. The y -intercept is the constant, represented by the variable b.
How to write a linear equation with a slope intercept?
Once the slope has been identified, write a linear equation in slope-intercept form (y = mx + b). Using one set of coordinates (x, y) and the slope m, rewrite the equation by substituting the appropriate values for x, y, and m. Then, solve the equation for b to identify the y-intercept.
