The first one because they go up by 4 each time thus it is linear.
Hope this helps! :)
Answer:
384cm^2,
Step-by-step explanation:
The top and bottom margins of a poster are each 6 cm and the side margins are each 4 cm. If the area of printed material on the poster is fixed at 384 cm^2,
I think 63, but I'm not sure, how do I delete an answer-
Answer <u>(assuming it can be put in point-slope format)</u>:
Step-by-step explanation:
You can write an equation of a line when knowing its slope and a line it passes through using point slope formula, 
.
1) First, find the slope of the equation. We know it has to be parallel to y = 3x + 2. Lines that are parallel have the same slope, thus the slope of y = 3x + 2 is the slope of the answer as well. y = 3x + 2 is in slope-intercept format, or 
. The coefficient of the x term, or 
, represents the slope - so, the slope must be 3.
2) Now, use point-slope formula,, to write the equation. Substitute , 
, and 
for real values.
The represents the slope, so substitute 3 for . The and represent the x and y values of a point the line crosses through. The line crosses through (2, -4), so substitute 2 for and -4 for . This gives the following answer:
