Answer:
Step-by-step explanation:
y = 3x + 2
Slope m = 3
slope of the line perpendicular to this line = -3
Point (3,5)
y- y1 = m(x-x1)
y - 5 = -3(x-3)
y - 5 = -3*x-3 * -3
y - 5 = -3x + 9
y = -3x + 9 +5
y = -3x + 14
Answer: See below
Explanation:
8x + 14 = 10x - 10 (alt. exterior angle)
8x - 10x = -10 - 14
-2x = -24
x = -24/-2
x = 12
Now plug x = 12 in 10x - 10 to find the angle:
10(12) - 10 = 120 - 10 = 110 degree
B. seven minutes - because that is when the slope of the line is flat, which means he isn't moving.
