How do you create a straight line graph?

Answer by  Hers (32)

All that is needed for a straight line graph, is two points (x,y) and (x1,y1). Connect the dots and ta-da!

Given an equation y=2x+1 This line has slope 2, and passes through the point (0,1)=(0,2X0+1). Draw a line through (0,1) that goes up 2 for every grid to the right.

You look at the equation. Then you fill in value x=0 and solve for y. You find a point (0,y) and draw it. Then you fill in value y=0 and solve for x. You find a point (x,0) and draw it. Connect these with the straight line graph.

By finding the tercept and x-intercept, then trace the graph, or by giving points to the equation,that gives you the behavior of the slope if its negative, positive, equal to zero, or no slope and the tercept, by the equation f(x)=mx+b

If you have data, just draw straight from the data. If you do not have data, make sure the equation fits y = mx + c where m is the gradient of the graph.

Answer by  bon (39)

This kind of graph is called a linear graph and it is made by any interaction between X and Y, such as X = 2Y or Y = -(3X). The results of these interactions are plotted on two axes, called X and Y. Conventionally X is the horizontal axis and Y the vertical.

Answer by  noguf (162)

A vertical line called the y-axis and a horizontal line called the x-axis make an L shape. The line itself can be made by drawing any two points that you want to have on the line and joining them. Make arrows at either end of the line.
