Web24 okt. 2013 · We are given: (1) d y d x = 3 y − 7 x + 7 3 x − 7 y − 3. It would really be nice if we could get rid of those constants, so lets use a trick to do that. Let: X = x + h → d X = d x, Y = y + k → d Y = d y. We substitute into ( 1) and get: (2) d Y d X = 3 ( y + k) − 7 ( x + h) + 7 3 ( x + h) − 7 ( y + k) − 3. WebFinally, we will solve 7x - 3y = 21 for x and also for y, then calculate and show you the solution for the slope of 7x - 3y = 21. Find x-intercept The x-intercept is where the graph crosses the x-axis. To find the x-intercept, we set y 1 =0 and then solve for x. 7x - …
