2. a style of dance music marked by some of the features of jazz.
The graph of y = 2x+1 is a straight line. 1  When x increases, y increases twice as fast, hence 2x. 2  When x is 0, y is already 1.  So: y = 2x + 1.
Determine the value of the slope of a line from a table or a graph. Proportional Relationships. Determine whether a linear function is a direct variation. Solve problems involving direct variation. Compare proportional and non-proportional linear functions in the form of a table, graph and equation. Slope Intercept Form. Analyze a graph to determine slope and y-intercept. Graph a linear function using the slope and y-intercept. Write a linear equation in slope-intercept form given the slope and y-intercept. Standard Form. Analyze a linear graph to determine the intercepts. Write linear equations in standard form to model real world scenarios. Determine and interpret the intercepts of a linear function from an equation in standard form.
