Answer:
(a) Verified
(b) They are simultaneous equations
Step-by-step explanation:
Given


Required
Verify that:
is a solution
We have:

Substitute:

Evaluate all products

Subtract:

<em>Because both sides of the equation are equal, then the point is a solution</em>
<em></em>
Also: 
Substitute:

Evaluate all products

Subtract:

<em>Because both sides of the equation are equal, then the point is a solution</em>
<em></em>
<em></em>
Because the given point is a solution to both equations, then they are simultaneous equation
Given the points (-1,6) and (3,5).
The formula to find the slope is

Take

Plug the values into the formula and find the slope.

The slope-intercept form is y = mx+b.
Plug the value of m.

ThusConsider the point (-1,6). Substitute -1 for x and for y into the equation.

Thus, the equation of the line in slope intercept form is

Heya! Princess Kimmie 
Let the Direct Variation Equation of Given Ordered pairs be : y = nx
Given : y = 4.8 when x = 4
Substituting the above values in our Equation, we get :
⇒ 4.8 = n × 4
⇒ 
⇒ The Equation is y = 1.2x
Option 3 is the Answer 
I think it is c but I don’t know
