Answer:
C. y = 1½x + 9
Step-by-step explanation:
The quickest way is to know what intercepts are shown here and you are done, but if you want to, then all you have to do is plug in each number given to you into each solution to confirm the authentication.

The general equation of a linear data is [tex]y = mx + c[/tex], where m is the slope, and c is the y intercept. The equation that satisfies the data is: [tex]y =\frac{3}{2}x +9[/tex]
Given:
[tex]x \to -6\ |\ 0\ |\ 6[/tex]
[tex]y \to 0\ |\ 9\ |\ 18[/tex]
First, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{9-0}{0--6}[/tex]
[tex]m = \frac{9}{6}[/tex]
Simplify
[tex]m = \frac{3}{2}[/tex]
The equation of the table is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
This gives:
[tex]y =\frac{3}{2}(x - -6) + 0[/tex]
[tex]y =\frac{3}{2}(x +6)[/tex]
Open bracket
[tex]y =\frac{3}{2}x +9[/tex]
Hence, the equation that satisfies the data is: [tex]y =\frac{3}{2}x +9[/tex]
