Question

Which equation describes the line with a slope of -3 and passes through the point (-4,0) and how do you know?

a) y+3 = -4(x-7)
b) y-7 = -3(x+4)
c) y-7 = -4(x+3)
d) y+4 = -3(x-7)

Answer 1

y=-4x+28
y=-4x+25 


y=-3x-12
y=-3x-5 


y=-4x-12
y=-4x-4 

y=mx+b 
m=slope 
b= y intercept 

C is the answer
