Graph lines using a slope and a y-intercept. Identify the slope and y-intercept from the equation of a line in slope-intercept form. This activity is useful for algebra students learning to graph lines for the first time, or for students who may need extra help or review with this topic. y=mx+b is the second of seven activities for teaching and learning linear equations in algebra: *Ski Slope*; ** y=mx+b**;

*Points, Intercepts, and Slopes, Oh My!*;

*Linear Word Problems*;

*Solving Systems of Equations by Graphing*;

*Systems of Equations Word Problems Part 1*;

*Systems of Equations Word Problems Part 2*.

**CCSS.Math.Content.HSA-CED.A.2** Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.

**CCSS.Math.Content.HSA-REI.D.10** Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line).

**CCSS.Math.Content.8.F.A.3** Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. For example, the function A = s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.

**CCSS.Math.Content.8.F.B.4** Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.
