how to do point slope equations. Start at your b value. It emphasizes the slope of the line and a point on the line that is not the y-intercept.
Investigate the relationships between linear equations slope and graphs of lines. The line crosses the y-axis at the point 0 -2. 4 2 parallel to y.
Have a play with it first move the point try different slopes.
M and want to find other points on the line. To write an equation in slope-intercept form given a graph of that equation pick two points on the line and use them to find the slope. Use our interactive html5 applet to explore the relationship between the equation of a line and its graph by clicking and dragging the point below around. In this case m 4.
