Parallel lines have the same gradient so it’s the second or the fourth answer.
y = mx + c
y = 2x + c
3 = (2 x 2) + c
3 = 4 + c
3 - 4 = c
c = -1
y = 2x - 1
Answer/Step-by-step explanation:
Given:
-x + 3x + 1 + 4(x + 2) = 54
To solve, first open the bracket by applying the distributive property. Multiply every term you have in the bracket by 4
-x + 3x + 1 + 4x + 8 = 54
Add like terms together
6x + 9 = 54
Subtract 9 from each side
6x = 54 - 9
6x = 45
Divide both sides by 6
x = 45/6
x = 7.5
Answer:
5/2
