can someone explain how to solve this.?

Question

y= -2x+3 how do i graph this

Answer 1

This is the equation of a straight line.
To draw a line, two points are required.
(0 , 3) and (4,- 5) are two points on the line.
Draw a line thro` these points.

Answer 2

The 3 hits the y-axis at (0,3). Graph that point. The -2x means that the change in (y/x) is sloping down (-2/1). The easiest way to do this is to start at the (0,3) point, and move down -2 spaces on the y values and over 1 spaces on the x values, and graph the next point, and repeat from there for a few more points and connect them all with a straight line. Then it's graphed.

...Or you just could use a TI-83 graphing calculator :P

Answer 3

If you have a graphing calculator, this should be simple. You take the Y= button on top and enter the equation in there and then push Graph. But if you don't here's the hard way.
1) x = the slope correct and 3 = the y-intercept.
2) the line will go through the postive 3 on the y axis. \ the line will go like that and hit the 1 on the x-axis

Answer 4

This is an equation of a straight line.

To draw a straight line, you will need to know at least two points.

For the equation:

y = -2x + 3

The first easy point is when x = 0.

y = -2(0) + 3

y = 3

This is call the y-intercept because it is marked on the y-axis itself.

So, you mark an "X" on the first point (0, 3).

For the second point, just let x = 1,

y = -2(1) + 3

y = 1

Now, mark another "X" on the second point (1, 1).

Then draw a straight line passing through these two points, (0, 3) and (1,1).

Done.

Answer 5

y=-2x+3;
when x=0,y=3, so this point isA(0,3).
when y=0, x=3/2=1.5, this point isB (1.5,0).
Plot the pointsA&B and the straight line.passing through A&B is the desired Graph.

Answer 6

The slope is -2, and the y-intercept is at 3.

Answer 7

Over what range of 'x' values?

Can you multiply -2 times some values of x that you are interested in seeing? (values can be negative as well as positive)

You'll yield some values of 'y', then plot those on graph paper - for each value of 'x', you'll have a 'y' value.
