Answer:I don't know if you're asking for equation or not cause you didn't mention the question so I'm just gonna write down the equation.
y=4.2x+3.4
Use this formula➡️y=mx+b
m is slope, b is y-intercept , x and y are the points like (0, 3.4)
You said it's the y-intercept but it's not. it's just a point on the graph
Step-by-step explanation:
Get x to one side by subtracting 2x by 5x.
-3x = -30
Then divide both sides by -3 to get x = 10
Have a nice day.
I think that it would be C, but I am debating on C and D. I'm pretty confident that it's C, though. Pretty sure.
