Answer:
y +5 = -1/3(x -3)
Step-by-step explanation:
The slope of the given line is 3. The slope of the perpendicular line is the negative reciprocal of that, -1/3. Then the point-slope equation is ...
y -y1 = m(x -x1) . . . . line with slope m through point (x1, y1)
y -(-5) = -1/3(x -3)
y +5 = -1/3(x -3)
Answer:
n = 1.125
Step-by-step explanation:

(Use Cross Product)
40n = 15 × 3
40n = 45
n = 1.125
The answer is A. because if she read 4 times as much, p multiplied by 4= 40
