Answer:
m = 3 and c = - 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 )
y = 3x + 2 ← is in slope- intercept form
with m = 3
• Parallel lines have equal slopes, thus
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (1, 2) into the partial equation
2 = 3 + c ⇒ c = 2 - 3 = - 1
y = 3x - 1 ← equation of parallel line
with m = 3 and c = - 1

Answer: 0.6 grams per cm</h3>
===================================================
Explanation:
Pick any column and divide the weight over the length
column 1: 9/15 = 0.6
column 2: 12/20 = 0.6
column 3: 18/30 = 0.6
column 4: 30/50 = 0.6
The weight per cm is 0.6 grams per cm
---------
Another way you could look at is like so
9 g = 15 cm
9/15 g = 15/15 cm
0.6 g = 1 cm
We divided both sides by 15 to turn "15 cm" into "1 cm". Think of "per cm" as "per 1 cm". This works for any other column as well.
