Answer 1

Which line is a graph of the equation: 2x + 5y = –10?
Number graph ranging from negative five to five on the x axis and negative six to two on the y axis. Four lines are drawn in blue on the graph. Lines a and c have a positive slope and are parallel to each other. Lines b and d have a negative slope and are parallel to each other. Lines a and b intersect at (zero, two), and lines c and d intersect at (zero, negative two).

Answer 3

i think i get -5,-2? but I AM CONFUSED

Answer 4

2x + 5y = -10
5y = -2x - 10
y = -2/5x - 2

so in this equation, your y int is (0,-2)
to find your x int, sub in 0 for y

2x + 5(0) = -10
2x = -10
x = -5
and you x int is (-5,0)

now which line has the points (0,-2) and (-5,0) ?

Answer 5

right i knew that.......... so line c

Answer 6

XD

Answer 7

not C......try again....(-5,0)...and (0,-2)

Answer 8

oh a sorry

Answer 9

i got mixed up

Answer 10

not A......points are always set up like this (x,y).....take a look at line D. Are your points on this line ?

Answer 11

those negatives will mess with your brain...lol

Answer 12

yes im sorry I do not have my contacts in and it is a small graph and i can not see very well

Answer 13

no need to apologize.....it is kinda small. It is D.

Answer 14
