Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
we know that
If the point belongs to the graph, then the point must satisfy the equation
we will proceed to verify each case
<u>case A.)</u> 
The point is 
Verify if the point satisfy the equation
For
find the value of y in the equation and compare with the y-coordinate of the point



therefore
the equation
not passes through the point 
<u>case B.)</u> 
The point is 
Verify if the point satisfy the equation
For
find the value of y in the equation and compare with the y-coordinate of the point



therefore
the equation
passes through the point 
<u>case C.)</u>
