Establish the equation of the line in slope-intercept form
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁) = (- 3, - 3 ) and (x₂, y₂) = (3, - 1) ← 2 points on the line
m = 
= 
= 
the y-intercept is (0 , - 2 ) ⇒ c = - 2
y = x - 2 ← equation of line
This is a strict inequality since the line is broken, hence
y > x - 2 → B
19. 10 divided by 3 = 5 pounds
20. 5.5 divided by .5 = 11
21. no because 1.25 x 2.5 = 3.12 and she only has $3
22. the restaurant because the restaurant wants to buy 30lb and its $1.25 so 30 x 1.25 = 37.5 and the hotel buys 12 lb for $3 so that is 12 x 3= 36

Answer:
y=5 and x=4
Step-by-step explanation:
So,the diagonals of a parallelogram bisect each other..
therefore,we have our two eqn
4x-2=3y-1------------(i)
3y-3=3x
or,y-1=x----------(ii)
Now,simply substitute value of x in eqn (i)
4(y-1)-2=3y-1
or,4y-4-2=3y-1
or,y=5
Again,substitute y=5 in eqn (ii)
5-1=x
therefore,
x=5
Hope it helps you!!!
