Select the equation in which the graph of the line has a negative slope, and the y-intercept equals 10.

Answer

10x + 5y = –25

5x – 10y = –12

20x + 5y = 50

2x + 6y = 10

I think this is it 20x + 5y = 50

anonymous · Answer

Since 20x does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 20x from both sides
5y=-20x+50
move all the terms not containing y to the right
5y=50-20x
5y/5=50/5 - 20x/5
simplify the left side by cancelling out common factors
y=50/5-20x/5
simplify 
y=10-4x
Using the y=mx+b formula, m=-4 and b=10
