2y = 8x + 6
y = 4x + 3
The graph is a straight line passing through points (0, 3) and (-3/4, 0) with slope = 4.
We have to draw the model for 5 divide 1/7 . In order to draw the model we use below steps.
Draw 1/7 boxes to represent 1/7 groups.
Assume 5 as the number which represents the total of these 1/7 groups.
Put a question mark at the first box.
Attached is the model to represents 5 divide 1/ 7 .
5/(1/7)
5*7
35
In the question mark we should put 35.

#SPJ9
2 is the lie and 1 and 3 are truths
Step-by-step explanation:
#1 : if you looking for x intercepts make y=0
0=2x^2+4x
0=2(x^2+2x)
Divide both sides by 2
0=x^2+2x
0=x(x+2)
Therefore x=0 or x=-2
1 is true
#2
We can sub in the value to see if it is true
2(-14,70)^2-42(-14.70)=1049,58
Therefore 2 is a lie
#3
we can solve
To find x we make y=0
0=3(x-5)^2-12
0=3(x^2-10x+25)-12
0=3x^2-30x+75-12
0=3x^2-30x+63
0=3(x^2-10x+21)
Divide both sides by 3
x^2-10x+21=0
Factorise
(x-7)(x-3)=0
Therefore x=7 or x=3
Therefore 3 is a truth
