Answer:
15x + 14y = -218
Step-by-step explanation:
To write the equation of a line when given two points, calculate the slope and substitute it into the point slope form of a line. From this form of the equation, you can simplify and convert to the standard form.
First, find the slope using the formula.
![m = \frac{y_2-y_1}{x_2-x_1} =\frac{6--9}{-8-6} =\frac{15}{-14}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%3D%5Cfrac%7B6--9%7D%7B-8-6%7D%20%3D%5Cfrac%7B15%7D%7B-14%7D)
Substitute m = -15/14 and the point (-8,6) into the point slope form
.
![y-6=\frac{-15}{14}(x--8)\\y - 6 = \frac{-15}{14}(x+8)\\14y + 98 = -15(x + 8)\\14y + 98 = -15x - 120\\15x + 14y + 98 = -120\\15x + 14y = -218](https://tex.z-dn.net/?f=y-6%3D%5Cfrac%7B-15%7D%7B14%7D%28x--8%29%5C%5Cy%20-%206%20%3D%20%5Cfrac%7B-15%7D%7B14%7D%28x%2B8%29%5C%5C14y%20%2B%2098%20%3D%20-15%28x%20%2B%208%29%5C%5C14y%20%2B%2098%20%3D%20-15x%20-%20120%5C%5C15x%20%2B%2014y%20%2B%2098%20%3D%20-120%5C%5C15x%20%2B%2014y%20%3D%20-218)
To convert to standard form, multiply the equation by 14. This means each term is multiplied by 14 to clear the denominator. Then multiply using the distributive property. You will now need to move terms across the equal sign. Begin by adding 15x to both sides. Lastly, subtract 98 from both side.
Answer:
$625
Step-by-step explanation:
25% more as a whole number would be 1.25 (since you need to include the original 100 percent)
multiply 500 by 1.25 to get your retail price, 625
Answer:x=2 y=-2
Step-by-step explanation:
Fill it in it’s right use substitute or elimination to get it
Let's make our equation in the form of y = mx + b
<span> 2x – 6y = 9
Add 6y on both sides
2x = 6y + 9
Subtract 9 on both sides
6y = 2x - 9
Divide 6 on both sides
y = 1/3 - 3/2
Now, we have it in the form of y = mx + b
In y = mx + b, m is the slope and b is the y-intercept
That means in y = 1/3 - 3/2, the slope is A) 1/3.
Your answer is A) 1/3</span>
