Question

Which line is a graph of the equation: 2x + 5y = -10?

line a

line b

line c

line d

Answer 1

D

Explanation:

2x + 5y = - 10 Subtract 2x from both sides

5y = -2x - 10 Divide by 5

y = -2x/5 - 10/5

y = 0.4x - 2

The slope is minus so the line is going from lower right to upper left as B and D are doing.

The y intercept is - 2. B goes through + 2 so it is not the answer.

The answer is D
