Answer:
x = 2
Step-by-step explanation:
This blue line seems to be horizontal, and so a line perpendicular would have to be vertical. The only vertical line that passes through (2, 6) would be x = 2.

Answer:
2x
Step-by-step explanation:
because we need to make it equal
Answer:
y=4/3 -1
Step-by-step explanation:
A linear equation would be y=mx+b.
The b is the y-intercept which in this case would be -1.
There are two ways to find m (slope) rise over run or the way I'm about to do.
Take the two points (3,3) and (0,-1)

That would make m = 4/3.
Answer:
A and C
Step-by-step explanation:
Step 1: Replace x with 2.5 and see if it makes the equation correct.
A. |2 1/2 + x = 5| Since 2 and 1/2 is also written as 2.5, and 2.5+2.5=5, the solution makes this equation true.
B. |25x = 63| 25 x 2.5 equals 62.5, which does not make this equation true because 63 ≠ 62.5
C. |6.75x + 4.25x = 27.5| I Rewrite this equation as
(6.75 x 2.5) + (4.25 x 2.5) which can simplify to 16.875 + 10.625 and it does in fact equal 27.5, so this solution does make the equation true.
Step 2: Eliminate the equation(s) that aren't true, and then answer.
A and C are correct.
