Y intercept equation

How do you find the Y intercept?

How Do You Find the X- and Y-Intercepts of a Line in Slope-Intercept Form? To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’. To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’.

What is the Y intercept of y =- 3?

Algebra Examples Using the slope-intercept form, the y-intercept is −3 .

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

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

What is Y intercept in math definition?

: the y-coordinate of a point where a line, curve, or surface intersects the y-axis.

What is the Y intercept of y =- 3x 2?

The y-intercept is (0,−2) .

What’s the slope of y =- 3?

1 Expert Answer So the slope would be 0. Another way to think about slope is the rise (change in y) over the run (change in x). 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.

How do you find the Y intercept when given two points?

Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

What is the slope of y =- 5x 1?

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

What is Y intercept in graph?

The y -intercept of a graph is the point where the graph crosses the y -axis. For example, we say that the y -intercept of the line shown in the graph below is 3.5 . When the equation of a line is written in slope-intercept form ( y=mx+b ), the y -intercept b can be read immediately from the equation.

How do you interpret the slope and y intercept?

In the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the “slope-intercept form”.

What’s the slope of y =- 2x?

Explanation: The slope-intercept form is y=mx+b where m is the slope value. In the equation y=2x , the m value is 2 . Therefore, 2 is the slope.

Opportunity cost equation

What is the formula for opportunity cost? The formula for calculating an opportunity cost is simply the difference between the expected returns of each option. Say that you have option A: to invest in the stock market hoping to generate capital gain returns. In other words, by investing in the business, you would forgo the […]

Rewrite as a logarithmic equation

How do you write a logarithmic function? Then the logarithmic function is given by; f(x) = log b x = y, where b is the base, y is the exponent and x is the argument. The function f (x) = log b x is read as “log base b of x.” Logarithms are useful in […]
