# How to write a slope intercept equation with an undefined slope

Note that all the x values on this graph are 5. The symbols introduced in this chapter appear on the inside front covers. Looking at the graph, you can see that this graph never crosses the y-axis, therefore there is no y-intercept either. The lowest point of the roller coaster was actually built 10 feet below the ground. The components of an ordered pair x, y associated with a point in the plane are called the coordinates of the point; x is called the abscissa of the point and y is called the ordinate of the point.

Example 2 If a line has the equation then the slope of the line must be -2 and the y-intercept must be 8. This one is a little trickier. Pat yourself on the back if you said But notice how the graph is flipped, so we will use —sin. The slope and y-intercept can be obtained directly from an equation in this form.

Perpendicular Lines and Their Slopes In other words, perpendicular slopes are negative reciprocals of each other. In this form, m is the slope of the line and b isthe y intercept. Writing Equations from Transformed Graphs for Sec, Csc, Tan, and Cot Here are a few examples where we get the equations of trig functions other than sin and cos from graphs.

We can use 5 key points for a whole period of a graph. Yes, it is rising; therefore, your slope should be positive. For example, for any two distinct points, there is a unique line containing them, and any two distinct lines intersect in at most one point. We've now seen an example of a problem where you are given the slope and y-intercept Example 1.

How do write an equation of a line when given the slope a point of the line. The answer is the slope is 2 and the y-intercept is We need to do a little digging to get our slope. A positive attitude is an important aspect of the affective domain and has a profound effect on learning. Environments that create a sense of belonging, support risk taking and provide opportunities for success help students to develop and maintain positive attitudes and self-confidence.

in slope-intercept form of y = mx + b, the slope is m and the y-intercept point is (0,b) if slope is positive then the line rises upward from left to right if slope is negative. The slope is undefined! In fact, this is a special case, and we use a different equation, like this: x = (called the slope-intercept form of the equation of a line).

It is the same equation, in a different form! The "b" value (called the y-intercept) is where the line crosses the y. Enter the equation you want to plot, set the dependent variable if desired and click on the Graph button.
