Answer:
y= (1/4)x+2
Explanation:
Comparing y =-4x + 8 to the slope-intercept form y=mx+b
• Slope = -4.
Let the slope of the new line = m
Two lines are perpendicular if the product of their slopes is -1.
Therefore:

The slope of the perpendicular line = 1/4
Since the line passes through the point (8,4), we have:

The equation of the perpendicular line is y= (1/4)x+2
Answer:
y=14x-12
Step-by-step explanation:
in the standard format y=mx+b, m is the slope and b is the y-intercept, so this equation would be y=14x-12 since the slope is 14 and the y-intercept is -12.
Answer:
0.02
Step-by-step explanation:
Given:
4 rows of ten students.
Probability of a head or tail in a coin toss is 1/2
head: 20 students sitting in the first two rows as your sample
1/2 * 1/20 = 1/40
tail: 20 students sitting in the last two rows as your sample.
1/2 * 1/20 = 1/40
