How to write an equation in slope intercept form that is perpendicular

Y and x stand for the coordinates of any points on the line. Remember that slope is the change in y or rise over the change in x or run. Now, b gives us the value of y where x is zero, this is called the y-intercept or where the line will cross the y axis. Locate this point on the y axis.

How to write an equation in slope intercept form that is perpendicular

Perpendicular lines cross each other at a degree angle. Both sets of lines are important for many geometric proofs, so it is important to recognize them graphically and algebraically. You must know the structure of a straight-line equation before you can write equations for parallel or perpendicular lines.

Parallel Lines Write the equation for the first line and identify the slope and y-intercept. A line is parallel to another if their slopes are identical. Regardless of the magnitude of the new y-intercept, as long as the slope is identical, the two lines will be parallel.

how to write an equation in slope intercept form that is perpendicular

The angle of rotation is 90 degrees because a perpendicular line intersects the original line at 90 degrees. Tip For three-dimensional lines, the process is the same but the calculations are much more complex.

A study of Euler angles will help understand three-dimensional transformations.

Let’s say we are given an equation in a form other than \(\boldsymbol{y=mx+b}\) and we were asked to graph’s graph the line: \(x=7y+3\) We know that this equation is not in the slope-intercept form, and we must use what we’ve learned about algebra to somehow get it in the form we know.

how to write an equation in slope intercept form that is perpendicular

To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation.

Next, find the coordinates of the y-intercept--this should be of the form (0, b).
