Answer:
d fasho
Step-by-step explanation:
- A line passes through (9,2) and (12,-4).
- So, x = 9, y = 2
- x = 12, y = -4
<u>For </u><u>the </u><u>1</u><u>s</u><u>t</u><u> </u><u>equation</u><u>,</u><u> </u>
- 2x + y = 20
- Putting x = 9, y = 2
- or, 2 (9) + 2 = 20
- or, 18 + 2 = 20
- or, LHS = RHS
- Now, putting x = 12, y = -4 in the above equation, we have
- 2(12) + (-4) = 20
- or, 24 - 4 = 20
- or, LHS = RHS.
- So we can see that the first equation is the equation of the line.
- This is given in the graph in the picture.
- Like this way, if we check with other equations, we see that they are not the required equation of the line.

Hope you could get an idea from here.
Doubt clarification - use comment section.
There ya go that’s on the chart and pretty easy you should try it out it is actually kinda fun
