Graphing using intercepts (old) (video) Khan Academy
WebY-intercept = 4 or (0,4) Step 1: Plot the y-intercept on your graph. The y-intercept is 4, so I will plot the point (0,4) Step 2: From the y-intercept (0,4) use the slope to plot your next point. The slope is 2, so you will rise 2 (up) and run 1 (to the right). Step 3: Draw a line through your two points. This line represents the equation y ... WebVideo Transcripts Graphing by Slope Intercept Form So let's look at first what slope-intercept form is. Slope intercept form is actually y equals mx plus b. The reason why it is called slope intercept form is because it gives a slope and an intercept. So, here is your slope. Remember that slope is rise over run so this tells you how to move. WebTo use this you use point slope form. y - y1 = m (x - x1) where (x1, y1) is the point you want. and m is slope. So just fill in and solve. y - y1 = m (x - x1) with m = 3 and (x1, y1) = (-2,3) y - 3 = 3 (x - -2) If you prefer KC's way just start with y = 3x + b then b = y - 3x where you plug in (-2, 3) for x and y, or in other words: eaby automatic uhren
