Question

Determine the type of boundary line and shading for the graph of the inequality 3x + y (greater than or equal to) 10.
A) Dashed line with shading on the side that includes the origin.
B) Solid line with shading on the side that does not include the origin.
C) Dashed line with shading on the side that does not include the origin.
D) Solid line with shading on the side that includes the origin.

Answer 1

i know its either B or D

Answer 2

the question says...its greater...and the y-intercept is 10...and the slope is negative...what do u think...origin or no origin?...hint: u shade to the right when u have a negative slope and greater than sign

Answer 3

oh...u get that information when u put the question in slope intercept form, y=mx+b,
then, for this question, it will be....y = -3x + 10

Answer 4

so it will be.... B?...

Answer 5

perfect!

Answer 6

yayy!! thanks!!

Answer 7

no problem!:)
