WebIf the line goes straight up, then the line's equation is in the form x = ? because only the y value changes, the x value never changes. The x intercept is all you need to calculate for the equation because that x value is the same x value for every point on the line. So if your x intercept is (5,0) then your line's equation would be x = 5.

Where this line meets the vertical axis is ... rebecca wetzel attorney lynchburg vaWebTo find the slope of the line, pick two points on the line. Let's say we've looked at our graph, and have picked the points (3, 2) and (5, 6). Let's find how much the change in x aka the run is. To do that, we take the point with the greatest x value: (5,6) Find the x value of that point: 5 and subtract the x value of the other point. university of new south wales email address
