Answer:
y = 4x + 3
Step-by-step explanation:
To do this, put the new line into the form y = mx + b where m is the slope and b is the y-intercept.
When two lines are parallel, they have the same slope. Since, the slope of the first line is 4, that means the slope of the second line is also 4.
So far, the equation is y = 4x + b.
Then, since you know (-2, -5) is a solution, x = -2, y = -5 is a solution so you can plug this into the equation.
This would be:
-5 = 4 * -2 + b
-5 = -8 + b
3 = b
This means the equation is y = 4x + 3.
Answer
at first I said 1/2 but it's 2/5's.
Step-by-step explanation:

B..............
c>=3 and n<0 and p<=(9-3 c)/n
Answer:
48:76 would be 48/76 which would reduce to 12/19.
20:4 would be 5/1 reduced or just 5.
