Answer:
C. 2x +5y = -15
Step-by-step explanation:
You want the form ax +by = c. To get that form, you need to put the x-term on the left (making sure its sign is positive) and the constant on the right.
Multiply by 5:
5y +35 = -2(x -10)
Eliminate parentheses:
5y +35 = -2x +20
Add 2x-35
2x + 5y = -15 . . . . . . corresponds to selection C
