Question

x – 2y < 18
4x + y > –5

Explain, in complete sentences, how you would use the graphing method to solve the following system of inequalities and what the final solution will look like on the coordinate plane.

Answer 1

Just use Geogebra and describe it... o.O. and just use the slope and count rise over run and stuff o.o. substitute in what y equals and......color in the part that's lower than the part that isn't on 18 in the 1st graph or -5 U_U

Answer 2

first draw the graphs of the 2 lines x - 2y = 18
and 4x + y = -5
plot 3 points for each line

Answer 3

how would i find the points

Answer 4

just make them up
eg
let x = 0 then for x - 2y = 18, 0 - 2y = 18 , y = 18/-2 = -9 so plot the point (0,-9)

set up a table for each line

Answer 5

thankyou!

Answer 6

it will look something like this
