How do you graph y=x.. In words only please help?

Question

I need to know in words a step by step.. This is slope

Please help

Answer 1

Put some values for x and you will find y

x = -1 => y = -1 -> (-1,1)
x = 0 => y = 0 -> (0,0)
etc

Draw this points (you will need only two) and because y = x is a beeline just expand the line you draw.

Answer 2

simply set up a table of x and y

assign values to x and than solve for y

since x = y, for every value of x you choose, y will be the same

after you have a table of about 5 or 8 points, you have 5 to 8 pairs of points of x and y

on graph paper, call the horizontal axis the x axis and y the vert axis.

for the x point go to the right or left depending on the x you chose, and mark off that many units, and from here go up or down for the y value and plot that point. That point represents a point on the graph.

plot all your points and you will find that the graph is a straight line which goes through the origin., the line goes up and to the right and down and to the left. The slope of the this line is 1 since for every rise of y, you get the same run of x.

Answer 3

Any time you want to graph a line, just pick two points on that line. In this case, say you want to find the value of y at x=1. When x=1 , y=x, therefore a point on the line is (1,1). at x=5, y=x=5, therefore another point on the line is (5,5). Same with (0,0) and (-1,-1).

The slope is given by change in y divided by change in x. Therefore the slope is 1
Also the y-intercept is at (0,0)

Answer 4

Y = X is the straight line passing through the origin and having a slope of 1. Mark off some number of units to the right, then mark off the same number of units 'up'. Make a point at these coordinates, and draw a straight line from this point through the origin.

Answer 5

draw out your axis, label them etc.

plot a few points then join them up to make a line.
(u could draw a little table to make it easier then plot the points on the graph)

whatever the value of x is, the value of y must be the same because they are equal...

x I y the table of coordinates should look something
0 0 like this...then just plot the points and join them up
1 1
2 2
3 3

i hope this helps

Answer 6

Get some graphpaper. Draw X axis horizontal y axis vertical in centre of paper Where they cross is (0,0). Label suitably both x and y axis 1,2,3,4, etc.

Do a table of values for x and y . So as a clue when x=1 y=1.

When you have worked out four or five points mark their location on the graphpaper and join the points.

Answer 7

*draw two lines intersecting at a right angle
*draw a line intersecting both lines making a 45 degrees angle with the horizontal line and extend to both sides on the intersecting point
*put an arrow sign at both ends of third line
*mark the horizontal line as x and the vertical one as y

Answer 8

let's say it's y = mx + n

this equation defines a line and you can specify a line by two points.

It's easy,

put x = 0 and get y = n

put y = 0 and get x = - n / m

define these points and draw the line on the graph.

by the way slope is m

Answer 9

draw a line from the origin to 10,10 then extend the line as far as you want.
