Analyzing Linear Equations

Rate a ratio in which the two quantities being measured are in different units
Rate of Change used to describe how fast something is increasing or decreasing
Unit Rate a comparison of two quantities in which the denominator has a value of 1
Rise vertical change from one point to the next on a coordinate plane
Run horizontal change from one point to the next on a coordinate plane
Slope a mathematical term for rate of change
Slope-Intercept Form a linear equation: y=mx+b, where m is the slope of the line and b is the y-intercept
y-intercept the coordinates of a point where a graph crosses the y-axis
Direct Variation a proportional relationship where the graph is a straight line that goes through the origin
Point-Slope Form a linear equation: m(x-x1)=(y-y1), where (x1, y1) is a point the graph passes through and m is the slope
Standard Form a linear equation: Ax+By=C, where A, B, and C are constants and A and B are not both zero
