Equation Grapher. Description:: All Functions. Enter an Equation using the variables x and/or y and an =, press Go: Description . It can plot an equation where x and y are related somehow (not just y=...), like these:

GeoGebra was not so useful for this task. GeoGebra will give us the equation of a parabola, but you need to know the focus and directrix first. This is not so straightforward from observations of a graph. Conclusion. Finding the equation of a parabola given certain data points is a worthwhile skill in mathematics.

Write an equation in slope -intercept form of the line having the given slope and y-intercept or given points. Then graph the line. m : ±5, y-intercept: ±2 62/87,21 The slope -intercept form of a line of slope m and y-intercept b is given by y = mx + b. Here, m = ±5 and y-intercept = ±2. So, the equation of the line is y = ±5x ± 2.
