Start by distributing the - 1/3 which is the same as dividing the entire parentheses by 3 which results in (3x+10)
Answer: 
Step-by-step explanation:


A = -11
B= -12
This is because of how calculations work in negatives. Because they are both negative they work similarly to addition
Answer:
y = -5/4x - 4
Step-by-step explanation:
The equation they give you is in slope intercept form. y=mx+b. The m is the slope (-5/4). Since they want a parallel line you keep the same slope for point slope form. Point slope formula is y-y1=m(x-x1). the y1 and x1 are where you plug in the coordinates they give you.
y - 1 = -5/4x (x + 4)
y - 1 = -5/4x - 5
y = -5/4x - 4
