2018年5月10日 · b tends to be the y intercept which can be worked out given that you have the gradient and any coordinate of a point on that line. Just substitute them values in, rearrange to make b the subject which will give you the y-intercept (b). For example: y = 2x + b and you know that the coordinate (5, 2) lies on this function. Simple substitute them in and work out your …

2016年5月2日 · If #color(white)("XXX")y=mx+b#. subtracting #b# from both sides #color(white)("XXX")y-b=mx# dividing both sides by #m#

2012年9月5日 · To solve for m we want to get m by itself on one side of the equals sign, with everything else on the other side. First we subtract b from both sides, to get it out of the right side of the equation: y - b = mx + b - b. y - b = mx. Now we divide both sides by x, to get m completely by itself: (y-b)/x = (mx)/x (y-b)/x = m. So m is equal to (y-b)/x.

Gen, y=mx + b, Solve the equation for b means whatever operation done on one side of the equation has to be done on the other side of the equation. For example let's subtract mx from both sides of the equation: So: b=y-mx.

2017年7月22日 · Subtract color(red)(mx) from each side of the equation to solve for b: y - color(red)(mx) = mx - color(red)(mx) + b y - mx = 0 + b y - mx = b b = y - mx

2016年7月27日 · Subtract b from each side to get y-b=mx. Next, divide each side by x to get (y-b)/x=m.

The y-intercept, #b#, is found by plugging in #x=0# into the equation, which results in #y=b#, and therefore is the y-intercept. In some cases, if the equation is already arranged for you nicely, like #y=3x+5# , we can easily find the y-intercept for this line, which is #5# .

2019年6月26日 · In order to find "b" (the y-intercept) from the equation y=mx+b ... If you know the slope (m), use any one of the given points by substituting the Y value of the given point for y, and substituting the X value of the given point for x. Solve for b = Y-mX.

the standard form of y = mx + b becomes y = 2x + b now you take the point (x,y) = (3,5) that is on the line (has to be on the line) and replace x and y in the equation with it. the equation becomes 5 = 2*3 + b then you solve for b. in this case b = 5-1 = -1 your equation becomes y = 2x - 1 graph of that equation looks like: b is the y intercept ...

2014年10月7日 · The coordinates of a line or point on the x-axis will always have a y coordinate of 0. The following are examples of coordinates that lie on the x-axis. (-(3pi)/2,0) (0,0) the origin (-2,0) (3,0) (pi/2,0) To find the x-intercept you would substitute in the value of 0 for y variable and then solve for the x variable.
