Algebra. Graph x=4. x = 4 x = 4. Since x = 4 x = 4 is a vertical line, there is no y-intercept and the slope is undefined. Slope: Undefined. y-intercept: No y-intercept. Find two points on the line. x y 4 0 4 1 x y 4 0 4 1. Graph the line using the slope, y-intercept, and two points.
An interactive simulation to explore and practice graphing lines in slope-intercept form, connecting the slope and y-intercept to the equation.
Use the power of algebra to understand and interpret points and lines (something we typically do in geometry). Topics you'll explore include the slope and the equation of a line.
Example 8.9.10. Find the slope between the two points (4, 6) and (2, − 1). Solution. m = y2 − y1 x2 − x1 Substitute in the ordered-pairs m = − 1 − 6 2 − 4 Simplify m = − 7 − 2 Reduce, dividing by − 1 m = 7 2 Slope. Since this slope is 7 2, then the graph of this line would be rising left to right.
Learn how to graph a line using Slope and y-intercept. Know the equation of the line, identify the values of slope and y-intercept, and easily plot the line!
