Chapter 3 Vocab Flashcards
Linear equation
An equation that models a linear function
Direct Variation
A relationship that can be represented by a function in the form…
Parallel lines
Lines in the same plane that never intersect
Perpendicular lines
Lines that intersect to form right angles
Point-slope form
The point slope form of an equation of a non-vertical line with slope M and throughout point (x1,y1) is y-y1=m(x-x1)
Rate of change
Shows the relationship between two changing quantities.
Slope
The rate of change
Slope-intercept form
The slope intercept form of a linear equation is y=mx+b, where M is the slope of the line and B is the y-intercept.
Standard form
The standard form of a linear equation is Ax+By=C where A,B, and C are real numbers and A and B are not both zero.
X-intercept
The x-coordinate of a point where a graph crosses the x axis.
Y-intercept
A y-intercept of a graph is the y-coordinate of a point where the graph crosses the y-axis.
