Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values. Tap for more steps... Graph the line using the slope and the y-intercept, or the points.

3x+y +5 = 0 is the required equation of the straight line. graph { (3x+y+5) (x-3y-2)=0 [-8.44, 2.66, -4.17, 1.38]} Explanation: Any line perpendicular to ax+by +c = 0 ... The points of intersection of the curves satisfy the equations of both the curves.

Select a few x x values, and plug them into the equation to find the corresponding y y values. The x x values should be selected around the vertex. Tap for more steps... Graph the parabola using its properties and the selected points.

2017年12月12日 · The graph of the function y = x − 2 is a straight line with a slope of 1 and a y-intercept of -2. To graph it, start at (0, -2) and use the slope to find additional points such as (1, -1). Connecting these points creates the linear representation of the function.

2022年7月14日 · In this video we'll draw the graph for y = x - 2. You may also see this written as f(x) = x - 2. First, we will use a table of values to plot points on the g...
