The first two vertices are (-7,3) (-6,1)
Slope = (3 - 1)/(-7 + 6) = -2
Opposite side of the first two vertices so the lines are parallel.
Parallel lines, slope is the same so slope is also -2
Passing thru (-4,5)
y = mx + b
b = y - mx
b = 5 - (-2)(-4)
b = 1 - 8
b = -7
Equation:
y = -2x - 7

Answer:
$312
Step-by-step explanation:
Now, what we need to know is the cost of a melon since we know the cost of a bread fruit to be 8 yen.
What the question is simply saying is that the cost of 9 breadfruits and 10 melon equals the cost of 3 breadfruits and 12 melons.
To get her income per day, we need to get the amount she buys each melon. Let this amount be x yen.
Mathematically: 9(8 yen) + 10(x yen) = 3(8 yen) + 12(x yen)
Opening the brackets: 72 + 10x = 24 + 12x
48 = 2x , x = 24 yen
Her total daily income is thus 9(8) + 10(24) = 72 + 240 = $312
Yes y=x^2 is a function because Using the definition of a function, y=x^2 is a function because for every x-value in your domain, you will only get 1 unique y-value. A quick check you can do is to use the vertical line test
