Question

Write the slope-intercept inequality for the graph below. If necessary, use <= for or >= for

Answer 1

Where is the graph?

Answer 2

y-y1<m(x-x1) ?

Answer 3

the equation is y=mx+b.

Answer 4

so just substitute the letters for the numbers

Answer 5

0=4(-1)+b?

Answer 6

0=-4+b?

Answer 7

b=4

Answer 8

Okay well first off do you know how to find slope?

Answer 9

slope 4

Answer 10

correct. do you know the point-slope form?

Answer 11

no

Answer 12

okay so this is where its probably going to be important to know that formula. its: y-y1=m(x-x1)

Answer 13

so basically now you plug and chug

Answer 14

so pick a point, im going to pick (0,2) and then put it into the equation. you then get: y-2=4(x-0). now you solve for y.

Answer 15

y+2=4(x+1)

Answer 16

that works!

Answer 17

solve for y now :)

Answer 18

y=4x+2

Answer 19

correct! so now you have your equation, all you need to do is just figure out if you need a less than or equal to, or, a greater than or equal to symbol

Answer 20

y<4x+2?

Answer 21

<=

Answer 22

y<=4x+2?

Answer 23

give me one second to clarify

Answer 24

okay yes i agree! :) do you understand how i got the equation?
