Question

How can you graph y=x+7

Answer 1

So, have you picked any x values yet?

Answer 2

You need and x

Answer 3

Or you could use Desmos Graphing Calculator...

Answer 4

The homework im doing is Solve a system of equations by graphing and i have to graph
y=x+7 how can i do it?

Answer 5

well, have you ever graphed points before?

Answer 6

yes

Answer 7

would the cordinates be 1-7?

Answer 8

(1,7) sorry

Answer 9

so, if you put 0,1,-1 in for x, what y values will you get?

Answer 10

Go to this website and type in the equation.

Answer 11

I use that site all the time

Answer 12

that's not solving the problem people!

Answer 13

Anyways, it is in y=mx + b form (slope-intercept form).

Answer 14

Set your y intercept on a graph to positive 7 (b).

Answer 15

x is the slope. the slope is 1. so, just mark a rise and a run of 1, and draw a line through that.

Answer 16

It is a positive slope, so the line will go upwards. it is positive because x is positive, not negative

Answer 17

First. Understand that this makes a line. When you have an equation like so " y=x+7 " this makes a line on the y axis. But the point of intersection depends on the number on the other side of the line. http://www.wolframalpha.com/input/?i=y%3Dx%2B7

With this, find out the slope which is +7. The positive helps you decide whether it is ascending or descending.

Answer 18

Yep. thar ya go

Answer 19

But the slope is +1. The y-int is +7.

Answer 20

Just like with the example equation " y=m+x ", m is your point of intersection. A negative would have your line going down in numbers like so.... The number paired with x is your slope. please excuse the typo

Answer 21

Thank you

Answer 22

No worries! Sorry for the confusion
