Answer:
10y = 13x + 139
Step-by-step explanation:
Points (-5, -3) and (-15, -16) are the two points through which Line 1 passes.
So, the slope of the line 1 is 
Now, the slope of the parallel straight line i.e. line 2 will be same as line 1 i.e. 
Let us assume that the equation of line 2 is
{Where c is a constant} ....... (1)
Now, line 2 passes through the point (-13, 17). Hence, this point will satisfy equation (1).
So, 
⇒ 
Therefore, the equation of line 2 will be

⇒ 10y = 13x + 139 (Answer)

Answer:
The black tulle is the better buy
Step-by-step explanation:
You will need to find the unit rate for the tulle...in other words cost per 1 yard to see which is the better buy.
You also need to make sure they are in the same units. So, we will convert the 3 yards to feet....which will be 9 feet
5.63/9 = 0.62555 per foot
3.58/6 = 0.59666 per foot
X = math
y = history
x + y = 248
x + x - 68 = 248
2x = 316
x = 158
y = 90
