Nov 12, 2019 · y = the dependent variable, which is on the vertical axis (the ordinate) m = slope of the line described by the equation. x = independent variable, which is on the horizontal axis (the abscissa) b = y-coordinate of the y-intercept, which is the point where the line crosses the y-axis

Jun 26, 2019 · 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 value of b is the y-intercept, which is the point where the graph crosses the y-axis. The number m is the slope of the line, where slope m = rise over run. It gives the steepness of the line. And of course, x and y are variables which change within the graph from one point to another.

Dec 8, 2013 · Then in order to isolate the term with y, you would need to subtract 15 from both sides to give: 60x - 15 = -30y Now in order to "solve for y", you would divide by negative 30 to give you the final answer:-2x + 1/2 = y An easier way to solve this is to subtract the term 60x in the first place to get y alone, and then divide by positive 30.

Sep 5, 2012 · 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.

Oct 29, 2015 · 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.

Feb 6, 2014 · y=mx+b. The x is the first part of the (x,y) coordinate on a graph. For example, if a point on the graph ...

The formula y=mx+b describes a line in the Cartesian Coordinate System. A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length.

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:

Feb 13, 2022 · I had to pick an equation of line 1 in y=mx=b and I picked y=2x+7, how do I find three lines parallel to line 1 (y=2x+7)? So, I'm doing a math assignment where I have to make up an equation of a line in y=mx+b I picked y=2x+7 and now the next step is to find at least three other lines that are parallel to y=2x+7 My...
