Select the equation in which the graph of the line has a negative slope, and the y-intercept equals -5.
10x + 5y = –25
5x – 10y = –12
20x + 5y = 50
2x + 6y = 10
Always write the equation in y=mx+c format . In this format . m= slope and c = y-intercept
answer here will be equation A . Let me show you how.
or 5y=-10x -25
or y = -2x - 5
here you can see slope = m= -2 (-ve)
and y intercept =c=-5
you can also determine y-inetercept by putting x=0 . A line intersects at y-axis where its x-cordinate=0
so now , puttiing x=0
y= -2x0 + -5
I have showed it for option A which is correct . you can do the same for others too. You will see they wont satisfy the given condition.
