Answer: C) 0
Step-by-step explanation: Just took the test on edge
To deliver what is being asked of the given above, solve first for the slope of the line. Given two points the slope is calculated by,
m = (y2 - y1) / (x2 -x1)
m = (14 - 5) / (-2 - 1) = -3
Use the point - slope to write the equation of the line,
y - y2 = m(x - x2)
y - 14 = -3(x - -2)
<em> y = -3x + 8</em>
Therefore, the answer is letter D.
Answer:
By adding equation we get:
2x-y=3
x +y=9
______
3x=12
x=6
Step-by-step explanation:
cut the positive and negative (y)
To write and equation we call y=oil and x=vinager, so:

To find the constant k we can use the point in the picture (vinager, oil) = (x, y) = (1, 1.5), so:

So, the equation is:

Now, the meaning of the point (1, 1.5) is for 1 amount of vinager you need 1.5 amount of oil.
