What is the equation, in point-slope form, for a line that goes through(8,

LUCKY_DIMON [66]

Answer:

$\boxed{y-4=-\frac{5}{6}(x-8)}$

Step-by-step explanation:

Point slope form is: $y-y_1=m(x-x_1)$

$(x_1,y_1) - Coordinate\\ m- Slope$

We are given the slope of $-\frac{5}{6}$ and the point of (8,4).

Replace 'm' with -5/6, 'x1' with 8, and 'y1' with 4.

$y-y_1=m(x-x_1)\rightarrow \boxed{y-4=-\frac{5}{6}(x-8)}$

I do not see any options that match this, but the boxed equation should the correct answer.
