how can i make a table and graph this function y=2x+3?

Answer 1

To make your table, you merely select values of x, plug them into your equation, and write down the resulting values of y. Like this:

x | y
0 3
1 5

And so on. To graph the function, just plot the points in your table on the graph and draw a curve through them. In this case, your function is a straight line, and so any two points will be sufficient to draw the entire graph.

Answer 2

Pick any x you want and find y. (Small values of x will work better.) If x=2, then 2*2 + 3 is 7. To make the table, use two columns, one for x values and one for y values. Put 2 in the x column and 7 in the y column next to the 2. You can pick other values for x to complete the chart. Each x and y pair make one point on a graph. Then plot points on a graph. For example, the point (2, 7) is 2 blocks to the right and 7 blocks up from the origin. Now do other points. You should find that the points make a straight line. If not, then there is a mistake somewhere. The function you offered is an example of a linear equation.

Answer 3

The volume previously the variable is continuously the slope, and the volume through itself is continuously the Y intercept. For the first equation, -4 might want to be the point at which the line crosses the Y axis, and because that there is not any volume in the front of the x variable, a million/a million might want to be the slope. So plot a level on -4 on the Y axis, then count number up a million, over to the right a million (because it really is an excellent volume), and plot yet another factor. this grant you along with your graph. For the 2d equation, both through itself might want to be plotted on the Y axis at sensible 2. because the volume in the front of the x variable is two, your slope is two/a million. so that you count number up 2, over precise a million, and plot yet another factor. this gives you your 2d graph. in case you want to apply the numbers that the table says to apply, basically plug in the numbers it has chosen for x and y respectively into the equations, and use your innovations to devise the criteria.

Answer 4

The easiest thing to do....give values to x, and calculate y

if x=0......y=2*0 + 3=3
if x=1......y=2*1 + 3=5
and you can go on..
if x=2, 3, 4,......

Anyway, since this is the equation of a line, you only need two points to define it
-first point: (0; 3)
-2-nd point: (1; 5)

Draw this two points and than draw a line through them, as long as you can

Answer 5

Pretty simply, to tell you the truth!
......
x y
0 3
1 4
2 5
......
do u see a pattern?
the x axis is always 3 integars lower than the y axis.
Soz i cant actually show u a graph on this.
Hope it helps,

Answer 6

Plug in values of x and calculate y for each value of x.
Plot corresponding values of x and y

eg..

x y
1 5
2 7
0 3
-1 1

Now plot x and y values on the graph (1,5), (2,7), (0,3), (-1,1)

Answer 7

3 is the y-intercept, plot on (0,3) as the y-intercept. now go right 2 every one step up.
