Answer:
Step-by-step explanation:
slope = y2-y1/x2-x1
Given the coordinates (k,6k) and (3k,10k) 
x1 = k
y1 = 6k
x2 = 3k
y2 = 10k
Substitute
slope = 10k-6k/3k-k
slopw = 4k/2k
slope = 4/2
slope  = 2
Hence the slope of the line is 2
 
        
             
        
        
        
The equation can be used to solve for the measure of angle abc is sinx = 2.4/10.3
<h3 /><h3>SOH CAH TOA identity</h3>
The identity is used to find the measure of sides and acute angles of a right triangle
From the diagram shown, <ABC is the reference abgle hence;
Opposite side = 2,4cm
Hypotenuse .=10.3cm
According to the identity
sin x = opp/hyp
sinx = 2.4/10.3
sinx = 0.233
x =  13.47 degrees
Hence the equation can be used to solve for the measure of angle abc is sinx = 2.4/10.3

The answer is 1;3 because if you simplified 2;6 you get 1;3 so the answer to that is 
a: 1;3
