Finding y mx+b from graph
WebThis algebra video explains how to write a linear equation in slope intercept form y=mx+b. It also explains how to identify the slope and y-intercept from t... WebTo find the x-intercept we generally just use the same formula 'y=mx+b'. The reason that 'b' is the y-intercept is because at the 'y-axis, x=0'. By this I mean if you look at any graph, …

WebThis is the equation of a line on a graph, to solve this you must realise, the equation can also be written as 1y=1m1x-2. Y= The location of the point on the Y axis. X= The location of the point on the X axis. M= The slope. -2= Is the Y intercept, If there is a graph you can replace X and Y with the real co-ordinates, Ex: X=3 Y=5 5=3x-2.
WebApr 1, 2024 · One way to think of it is the fraction rise run. Let's say m = 1 - what that says is that for every step up (the rise) we move to the right 1 (the run). Now let's put it all together. Let's take y = x + 2. We have m = 1,b = 2. We can plot the y-intercept (0,2) and then move up 1 and to the right 1, which gives us (1,3). Webthe 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 which is the value of y when x = 0 which is -1. the graph confirms that. the slope is 2 which means that everytime x increases 1 unit, y increases 2 units. that can be seen on ...
