Question

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

A.10x+5y=-25
B.5x-10y=-12
C.20x+5y=50
D.2x+6y=10

Answer 1

That would be C.

20x + 5y = 50
5y = - 20x + 50
y = -20/5x + 50/5
y = - 4x + 10
now in y = mx + b form. the m represents ur slope and the b represents ur y intercept. So here, u have a slope of -4 and a y intercept of 10.
