p=price of television before reduction
7/10 = 30% reduction as 70/100 is 7/10.
-------------------------------------------------------
7/10*p=$161
7p=$1,610
p=($1,610)/7
p=$230
he example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7. Plug in the x value in to the first equation to find out the y value...

Answer:
y = (8/3)x - (2/3)
Step-by-step explanation:
<u>y1-y2</u>
x1-x2
(-6-2)/(-2-1) = (-8/-3) =8/3
So far we have y=(8/3)x
We can plug in one of the points given to find the y-intercept.
2=(8/3)(1)
2=(8/3)
(6/3) = (8/3)
This is false
To make it true we must subtract (2/3)
And that means the equation is
y = (8/3)x - (2/3)
I think its 6\5 but ill dont know how to explain it..
