Answer:
y -2 = 2(x -30)
Step-by-step explanation:
The point-slope equation is ...
y -k = m(x -h) . . . . . line through (h, k) with slope m
The slope formula is ...
m = (y2 -y1)/(x2 -x1)
m = (-28 -2)/(15 -30) = -30/-15 = 2
Using this slope and the first point, the equation of the line is ...
y -2 = 2(x -30)
