18x+10. I used the distributive property and then combined like terms. Please let me know if you want me to explain further!
Answer:
y = -
x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line
m =
= - 
Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = -
x - 1 ← equation of line
Answer:
parallel
Step-by-step explanation:
A (3,4), B (4,10)

C (-9,1), D (-7,13)
![Slope of CD = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\ =\frac{13-1}{-7-[-9]}\\\\ =\frac{12}{-7+9}\\\\ = \frac{12}{2}\\\\ = 6](https://tex.z-dn.net/?f=Slope%20of%20CD%20%3D%20%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C%5C%5C%20%20%20%3D%5Cfrac%7B13-1%7D%7B-7-%5B-9%5D%7D%5C%5C%5C%5C%20%20%20%3D%5Cfrac%7B12%7D%7B-7%2B9%7D%5C%5C%5C%5C%20%20%20%3D%20%5Cfrac%7B12%7D%7B2%7D%5C%5C%5C%5C%20%20%20%3D%206)
Slope of AB = Slope CD = 6
If two lines have same slope, they are parallel lines
