Explore slope-intercept form of a line connect the slope and y-intercept to the equation of the line challenge yourself in the line game graph a line given an equation in slope-intercept. These linear equations worksheets will produce problems for practicing graphing lines in slope-intercept form writing linear equations worksheets.
Video demonstrating how to write the equation of a line in slope-intercept form if given the slope and a point on the line using point-slope form or by graphing it. Equations that are written in slope intercept form are the easiest to graph and easiest to write given the proper information all you need to know is the slope (rate) and the y-intercept. Writing algebra equations finding the equation of a line given two points we have written the equation of a line in slope intercept form and standard form we have also written the equation. Equation of a line in slope intercept form, as well as how to find equation given slope and one point includes you-tube video lesson with pictures and many example problems.
If you know the slope, m, and y-intercept of the line (the point where the line crosses the y-axis), (0, b), of the graph of a line, you can write the equation in slope-intercept form. Unit 4: graphing/writing linear equations objectives: i can practice due date turned in section 41 i can write an equation in slope intercept form and graph the line using slope. Purplemath in the previous lesson, we saw the slope-intercept form for straight lines the other format for straight-line equations is called the point-slope form. You may already be familiar with the y=mx+b form (called the slope-intercept form of the equation of a line) it is the same equation, in a different form.
