How do you calculate a y-intercept?

The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero. 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.

How do you find slope-intercept form from points?

Steps to find the equation of a line from two points:

Find the slope using the slope formula.
Use the slope and one of the points to solve for the y-intercept (b).
Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.

What is the slope of y =- 5 4xy?

Pre-Algebra Examples Using the slope-intercept form, the slope is −4 .

How do u write an equation in slope-intercept form?

The slope-intercept form is one way to write a linear equation (the equation of a line). The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It’s usually easy to graph a line using y=mx+b.

How is the y-intercept represented in the slope-intercept form of a linear equation?

A linear equation has the form y = mx + b, where M and B are constants. By definition, the y-value of a linear equation when it crosses the x-axis will always be 0, since the x-axis is stationed at y = 0 on a graph. Consequently, to find a y-intercept, just substitute 0 for y and solve for x.

How do you convert y-intercept to standard form?

To convert from slope intercept form y = mx + b to standard form Ax + By + C = 0, let m = A/B, collect all terms on the left side of the equation and multiply by the denominator B to get rid of the fraction.
