the slope of the line is below 2. use the coordinates of the labeled point to find a point-slope equation of the line.
Allushta [10]

Answer:

C

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 2 and (a, b) = (1, 9) , thus

y - 9 = 2(x - 1) → C
