Question

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).



A.


line a


B.


line b


C.


line c


D.


line d



I think D

Answer 1

Answer 2

either c or D

Answer 3

@amistre64

Answer 4

5y= 2x+10

Divide each term in 5y=2x=10 by5

\[\frac{ 5y }{ 5 }=\frac{ 2x }{ 5 }+\frac{ 10 }{ 5 }\]

Cancel out the common factor

\[y=\frac{ 2x }{ 5 }+\frac{ 10 }{ 5 }\]

Divide 10 by 5 to get 2.

\[y=\frac{ 2x }{ 5 }+2\]

The slope- intercept form is y=mx+b

Slope:2/5
Y-intercept:2
