What are the intercepts of the equation 5x 3y 15?
What are the intercepts of the equation 5x 3y 15?
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -15/-3 = 5. Slope is -5/-3 = 1.
What is the slope of 6x 3y 15?
The line ax + by + c = 0 can be written as y = mx + c, where m is the slope of the line and c is the y-intercept. Therefore the slope is -2.
What is ordinate math?
In the coordinate system, the term “Ordinate” refers to the y -coordinate in (x, y). In short, the distance along the y-axis is called the ordinate. The term “coordinate” represents the position of the point along the line, arc and so on, whereas the term “ordinate” represents the value of a coordinate on the y-axis.
What do you call the first coordinate?
A relation is a set of ordered pairs. The first coordinate (usually the x-coordinate) is called the domain and the second (usually the y-coordinate) is called the range.
How do you do coordinate?
Coordinates are ordered pairs of numbers; the first number number indicates the point on the x axis and the second the point on the y axis. When reading or plotting coordinates you always go across first and then up (a good way to remember this is: ‘across the landing and up the stairs’).
How do you construct a coordinate plane?
To create a coordinate plane, start with a sheet of graph or grid paper. Next, draw a horizontal line. This line is called the x-axis and is used to locate values of x. To show that the axis actually goes on forever in both directions, use small arrowheads at each end of the line.
How do you convert Cartesian coordinates?
To convert from Polar Coordinates (r,θ) to Cartesian Coordinates (x,y) :
- x = r × cos( θ )
- y = r × sin( θ )
Does y go up or down?
The x-axis and y-axis are two lines that create the coordinate plane. The x-axis is a horizontal line and the y-axis is a vertical line. Reminder: the x-axis really runs left and right, and the y-axis runs up and down.
