WebCalculate the Straight Line Graph. If you know two points, and want to know the "y=mx+b" formula (see Equation of a Straight Line ), here is the tool for you. Just enter the two points below, the calculation is done live. Explore the Straight Line Graph Equation of a Straight Line Gradient (Slope) of a Straight Line Y Intercept of a Straight ... WebIf your equation is of the form: y=mx+b, then you do have a slope. The slope does not need to look like a fraction. For example: y=2x-5. The slope=2. As a fraction this is 2/1. y=x-5. The slope=1. As a fraction this is 1/1 y=0.5x-3. The slope=0.5, which in fraction form is 1/2 Hope this helps. 2 comments ( 12 votes) Upvote Downvote Flag more Andrew
Equation of a Straight Line - mathsisfun.com
WebThe equation of a straight line is usually written this way: y = mx + b (or "y = mx + c" in the UK see below) What does it stand for? y = how far up x = how far along m = Slope or Gradient (how steep the line is) b = value of … WebTo graph the equation of a line written in slope-intercept (y=mx+b) form, start by plotting the y-intercept, which is the b value. The y-intercept is where the line will cross the y-axis, so count up or down on the y-axis the number of units indicated by the b value. From the y-intercept point, use the slope to find a second point. The ... shark lesson
