Please help i have a headache and have been dong this for 2 hours straight please!!

Step-by-step explanation:

Let's break the price changes down:

Initial price: $896

On sale for 12%, meaning the computer will be 100-12=88% of the original price:

New sale price

Now a 7% tax is added to this, meaning the final price will be 107% of this new sale price.

Final price

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
