Answer:
y = -3x + 14
Step-by-step explanation:
y=x/3−1
The slope of the perpendicular line is the reciprocal of the given equation.
Given is 1/3x. Perpendicular slope is m=-3x
Substitute the perpendicular slope and the point (4,2) in an equation
y = mx + b
2 = -3(4) + b
2 = -12 + b
Find b by isolating
b = 2+12
b = 14
Substitute the slope -3x and b=14 to find the equation of the line.
y = mx + b
y = -3x + 14
<u>Explanation:</u>
The sign of the product of any odd number of negative integers is positive because when two minuses are multiplied with each other, it will result in a positive number.
<u>For example:</u>
- -3 x -5
- => -1 x -1 x (3 x 5)
- => 1 x (3 x 5)
- => 15 (Which is positive)

Answer: The general form for a line in slope-intercept will be y=mx+b.
Step-by-step explanation:
The equation of any line can be found in this form if the slope and y-intercept can be found and substituted in for m and b respectively.
Answer:
each penny is 1.52 millimeters high, and a stack of 20 pennies is 30.4 millimeters high
Step-by-step explanation:
18.24÷12= 1.52
