When we write a line equation in the form

m is the slope of the line, and q is the y-intercept.
Since we want the y-intercept to be -3, our line will look like

In order to fix the slope, remember that two parallel lines have the same slope. So, the slope of the given line y=2x-5 is 2, and since we want a line parallel to this line, our slope will be 2 as well.
Plugging the values, we can finish the equation:

Answer:
it would take 30 and a half days to make 240 cookies
The diagonals of a square bisect one another and are perpendicular.
so 21x+ 16.5 = 90
subtract 16.5 from each side
21x = 73.5
divide by 21 on each side
21x/21 = 73.5 /21
x = 3.5
31-62=152+2-6(3+21)
31-62=152+2-18+126
-31 =262
