Answer:
Step-by-step explanation:
step 1
Find the slope of the perpendicular line
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal
(the product of their slopes is equal to -1)
In this problem
we have
The equation of the given line is 
so
the slope of the perpendicular line to the given line is
step 2
Find the equation of the line in point slope form
we have
substitute
Convert to slope intercept form
Distribute right side
Answer:
$384.75
Step-by-step explanation:
Albert's hourly pay is $8.10
When he works for more than 40 hours, his hourly pay will increase to $12.15.
Last week, Albert worked for 45 hours, his hourly pay would be:
First 40 hours = $8.10 * 40 = $324
Remaining 5 hours =
$12.15 * 5 = $60.75
Albert gross pay for this period will be calculated as:
$324 + $60.75 = $384.75
Therefore, Albert gross pay for this period = $384.75
Y=7x+9 here’s your answer
Answer:
y = -2x + 12
Step-by-step explanation:
Step 1: find the slope
y = 1/2x + 5
The equation of the line is
y = mx + c
m - slope
m = 1/2
Note : if two lines are perpendicular to the other, both lines are negative reciprocal of each other
m = -2
Step 2 : using a point slope form
y - y1 = m( x - x1)
( 2 , 5)
x1 = 2
y1 = 5
y - 2 = -2( x - 5)
y - 2 = -2x + 10
y = -2x + 10 + 2
y = -2x + 12
The equation of the line is
y = -2x + 12
I dunno the answer so I just found another answer I found in here for this question:P
Sorry- it’s useless
