Question

Given the line 10x + 5y = -2 Find the y-coordinate that corresponds to x = 6. Round your answer to three decimal places.

Answer 1

plug in the x- coordinate in the equation then solve for y

Answer 2

Excellent advice. Alternately, you could solve in general, then substitute.\[10x + 5y = -2 \implies y=-2x-\frac{2}{5}\]You can put x=6 in and get y directly.

Answer 3

By either method, I think the answer is close to x = -12.400.
