Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
For lines to be parallel, they need to have the same slope.
To find the slope (m), use the slope formula:
And plug in the two points
(-2, 7) = (x₁, y₁)
(4, -5) = (x₂, y₂)
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
(two negative signs cancel each other out and become positive)
![m=\frac{-5-7}{4+2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-5-7%7D%7B4%2B2%7D)
Simplify the fraction
m = -2
The slope is -2, so the parallel line's slope is also -2.
Your answer is C
One of the three economic questions deals with deciding what goods and services must be produced from available resources.
Here are the Three Main Economic Questions
1) Who consumes the goods and services produced in society?
2) What goods and services must be produced in society?
3) How should goods and services be produced in society?
<span>These questions are very important because it deals on how available resources are allocated to produce essential goods and services demanded by consumer

Let g represent the number of gallons of ultra.
.. 1.603 = (1.80g +69.99)/(g +69.99/1.29)
.. 1.603(g +69.99/1.29) = 1.80g +69.99
.. 1.603(1.29g +69.99) = 1.29(1.80g +69.99)
.. 69.99(1.603 -1.29) = 1.29g(1.80 -1.603)
.. g = 69.99*(1.603 -1.29)/(1.29*(1.80 -1.603))
.. g ≈ 86.203
Edhelper Gas must sell 86.203 gallons of ultra to make the average selling price 1.603.
You need to find a common denominator, so 12. Convert the fractions:
9/12 + 10/12
Then add.
9/12 + 10/12 = 19/12
