4 Is the answer since 4 is x 4+4 is 8 8-4 is 4 :)
<span>( 5, 2) and ( 6, 4)
slope m = (4-2)/(6-5) = 2
y = mx + b
b = y - mx
b = 2 - 2(5)
b = 2 - 10
b = -8
so now you have slope m = 2 and y intercept b = -8
equation
y = 2x - 8
answer
</span><span>a. y = 2x - 8</span>
A.because -18 changes into positive and that would make it 18 + 12=30 and you divided it by -3x which should have x equal to -10
C.) 344.50
Take what she paid before tax (325) and multiply it by 1.06 (the tax rate) and there's your answer.
