Question

y = x + 4
y = –2x + 1

I need this graphed

Answer 1

Ok so you have a guess, with reasoning?

Answer 2

do you know how to find the x and y intercepts ?

Answer 3

I just dont have a graphing calculator on me..

Answer 4

Can you graph it without the calculator ?

Answer 5

And no, I forgot how to find the x and y intercepts

Answer 6

in y = mx + b form, the m is the slope and the b is the y intercept.
so in the first one...y = x + 4....the slope is 1 and the y intercept is 4 or (0,4)

to find the x intercept, sub in 0 for y
y = x + 4
0 = x + 4
-4 = x....the x intercept is (-4,0)

so plot your intercepts (0,4) and (-4,0)
start at x intercept (0,-4) and go up 1, and to the right 1, then up 1, and to the right 1 and you should cross the y intercept at (0,4)

Thats takes care of the first line
Can you do the second line ?

Answer 7

Probably

Answer 8

if you want to see the graph, go to mathway.com and it will show it

Answer 9

you probably already know this, but for the solution...it is where the 2 lines intersect

Answer 10

I've been trying to do that for the past 20 minutes and its not working

Answer 11

whats not working ?

Answer 12

It's not showing me the graph
It will give me one line but not the other

Answer 13

Its giving me the other line....just type in the other line right below the first line you typed in ....solution is (-1,3)

Answer 14

but it did graph it

Answer 15

or you can go to Quickmath.com....thats another site where you can graph it
