Below are the choices:
A.
<span>[8 -6] </span>
<span>[-5 4] </span>
<span>B. </span>
<span>[4 -3] </span>
<span>[-2.5 2] </span>
<span>C. </span>
<span>[-4 5] </span>
<span>[6 -8] </span>
<span>D. </span>
<span>[-2 2.5] </span>
<span>[3 -4]
</span>
B because it is the inverse of
<span>(4 6) </span>
<span>(5 8) </span>
<span>Check </span>
<span>(4.0 -3)(4 6) = (1 0) </span>
<span>(-2.5 2)(5 8) = (0 1)</span>
I think formula is y2-y1 divided by x2-x1 so if im correct
-5/-4
The straight line joining the points A(3,-5) and B(6,k) has a gradient of 4.
Gradient is the slope
So the slope of the line joining the points A(3,-5) and B(6,k) is 4
Slope of line joining two points = 
A(3,-5) and B(6,k) are (x1,y1) and (x2,y2)
slope = 
slope = 
We know slope =4

Cross multiply and solve for k
k + 5 = 12
k = 7
The value of k = 7
