Question

How do i graph this

y≥−1/2x+1

Answer 1

Are you familiar with the y = mx + b standard form?

Answer 2

yes

Answer 3

what you must do is use the clues from this form. First, you must graph the line, as an inequality indicates you will have a highlighted area as well as a line.

Answer 4

so -1/2 is the slope and 1 is the y intercept

Answer 5

Ok I think thats the problem i need help with like i don't know how to graph that. I know what the y-intercept is and the slope but I completely forgot how to graph it.

Answer 6

Do i start with 1 on the graph?

Answer 7

you can start wherever. But you have your y-intercept point because the slope is a negative number that means the line will have a negative track. Slope is rise divided by the run. Do you follow?

Answer 8

yes

Answer 9

oh wait so is the slope is a whole number then i put it in a fraction?

Answer 10

if*

Answer 11

so you must creat your next point by going down -1(the rise) and 2 units right(the run)

Answer 12

a slope can sometimes be a whole number or a fraction. Because we know its a fraction that is equivalent to rise/ run = -1/2

Answer 13

So if i graph that it would look like this https://prnt.sc/p9uj2p

Answer 14

but the line would be solid

Answer 15

I cant read this. Try using desmos graphing. https://www.desmos.com/calculator

Answer 16

here you can sign up for free using google, then you have the option to share your graph

Answer 17

I have no idea how to use this thing

Answer 18

just input

Answer 19

oh ok

Answer 20

just inout your inequality wher I have it,

Answer 22

that is correct. Now remember when graphing it without a program like this, you must know hat area to shade and whether to include the line or not. follow these rules:
