Answer:

"passes through the point (2,8). " . . . passes through the .2, eight." is very awkward, and incorrect.

Explanation:

Let's rewrite "A student writes the equation for a line that has a slope of -6 and passes through the .2, eight" to:

A student writes the equation for a line that has a slope of -6 and passes through (2, 8).

We can write y = -6x + b since we know the slope, m, to be -6.

We know the line goes through point (2,8), so use those values to find b:

y = -6x + b

8 = -6*2 + b for (2,8)

8 = -12 + b

b = 20

The equation is y = -6x + 20

See the attached graph.

It is unclear what word is incorrect. " . . . passes through the .2, eight." is very awkward and should read "passes through the point (2,8).
