Y=5
the difference between the x coordinates of each point is 6. in order for the slope to simplify to 2/3 the difference in y should be 9.
y=9-4(y coordinates of A)

Factorising quadratic expressions
Multiply these brackets to remind yourself how to factorise.
<span><span>( x + 2 ) ( x + 5 ) = x2 + 7x + 10</span><span>( x + 2 ) ( x + 3 ) = x2 + 5x + 6</span><span>( x - 3 ) ( x - 5 ) = x 2 - 8x + 15</span><span>( x + 6 ) ( x - 5 ) = x2 + x - 30</span><span>( x - 6 ) ( x + 5 ) = x2 - x - 30</span></span>
Because multiply of these two number get you -32, one of these number must be negative.
And because sum of them are positive, positive number must be larger than that negative number (without minus sign)
So list of possible answers are:
-1, 32; -2, 16; -4, 8
And we can see that
-4+8 = 4
So these two numbers are 8 and -4.
