The graph represents this system of equations:
2 answers:
Answer:
Option D is the correct answer.
Step-by-step explanation:
Refer the given figure showing the graph.
We can see the point of intersection is (2.5, -2).
Option D is the correct answer.
<u>Alternatively:</u>
2x + y = 3 ---------------------eqn 1
2x - 5y = 15 ---------------------eqn 2
eqn1 - eqn 2 gives
2x + y - ( 2x - 5y) = 3 - 15
6y = -12
y = -2
Substituting in eqn 1
2x - 2 = 3
x = 2.5
Point of intersection is (2.5, -2).
Option D is the correct answer.

The first table is a quadratic function while the second table is a linear function.
<h3>How to Interpret Function Tables?</h3>
1) For the first table, we have;
x y
0 5
1 0
2 -3
3 -4
4 -3
x = 2 and x = 4 have same value of y = -3 and as such it will be a Quadratic Function.
y = x² - 6x + 5
2) For the second table, we have;
x y
2 5
5 14
6 17
8 23
10 29
This table is a Linear function because slope is same and equal to 3 all through. Thus, the equation is y = 3x - 1
3) For the third table, we have;
x y
-3 8
-2 4
-1 2
0 1
1 0.5
This is an exponential function because equation can be modelled by;
y = 2⁻ˣ
