In this video we'll draw the graph for y = 3x + 2. You may also see this written as f (x) = 3x + 2. First, we will use a table of values to plot points on the...
Look now at the graphs of the two equations and note that the graph of y = 3x + 2 seems to have the same slope as y = 3x. Also note that if the entire graph of y = 3x is moved upward two units, it will be identical with the graph of y = 3x + 2.
A table and graph that represents the linear function y = 3x + 2 is shown in the image below. What is the slope-intercept form? In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation; y = mx + b Where: m represent the slope or rate of change. x and y are the points.

For y = 3x + 2, the slope is 3 and the y-intercept is 2. On a graph with x-axis and y-axis, locate the point (0, 2). Mark this with a dot. The slope is 3, which should be considered as 3/1 for graphing purposes. Begin at the point (0,2) and count upward 3 units, then go the right 1 unit and plot that point.

The x-coordinate of the point where a line crosses the x-axis is called the x-intercept of the line, and the y-coordinate of the point where a line crosses the y-axis is called they-intercept of the line. Using the intercepts to graph an equation is called the intercept method of graphing.

The graph of the given linear equation, y = 3x - 2, can be drawn as shown in the coordinate plane attached below. How to Graph a Linear Equation? To **graph **y = 3x - 2, choose x-values, calculate the corresponding y-values by substituting them into the equation, plot the points on a coordinate plane, and draw a straight line.
Graph the line using the slope and the y-intercept, or the points.
After finding 2 or 3 coordinates you can use a ruler to draw a line through the plotted points and that would be your graph. Another way to answer this question would be to plug different values of x into the equation and find the corresponding y values. For example you could plug 0 in and the y value would equal (3 x 0) + 2 = 2.

In this formula : y tells us how far up the line goes x tells us how far along m is the Slope or Gradient i.e. how steep the line is b is the Y-intercept i.e. where the line crosses the Y axis The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-3x-2 = 0 and calculate its properties
