Answer:
3/2
Step-by-step explanation:
First, let's simplify the given equation to make it easier to see the gradient (slope).
2y = 3x - 4 (Given)
y = 3/2x - 2 (Divided 2 on both sides)
Now, we can see that the gradient of the given line is 3/2. Since line AB is parallel to the given line, it will have the same gradient. Therefore, line AB's gradient is 3/2.

Answer:
(8.5, - 2 )
Step-by-step explanation:
Given the 2 equations
6x + 4y = 43 → (1)
2x - 3y = 23 → (2)
Multiplying (2) by - 3 and adding to (1) will eliminate the term in x
- 6x + 9y = - 69 → (3)
Add (1) and (3) term by term to eliminate x, that is
13y = - 26 ( divide both sides by 13 )
y = - 2
Substitute y = - 2 in either of the 2 equations and solve for x
Substituting into (1)
6x + 4(- 2) = 43
6x - 8 = 43 ( add 8 to both sides )
6x = 51 ( divide both sides by 6 )
x = 8.5
Solution is (8.5, - 2 )
5y<7 <------- That is the answer. BTW (by the way) the variable needs to always be on the rights side.
Hope this helps!!!!!!!!!
