Answer:
y=-1/4x+5
Step-by-step explanation:
perpendicular lines have slopes that multiply to -1.
Our given line:
y=4x-5
the slope (m) in it is 4. To find the slope of the perpendicular line:
4m=-1
divide by 4
m=-1/4
the slope of the new line is -1/4
here's our equation so far:
y=-1/4x+b
Since the line will pass through the point (-4,6) we can use it to solve for b (y intercept)
so substitute (-4,6) into the equation
6=-1/4(-4)+b
6=1+b
5=b
the y intercept is 5
so our equation is:
y=-1/4x+5
hope this helps! :D
The answer would be A because you would just plug in 2 everywhere where you see x
Answer:320ft^2
Step-by-step explanation:
80% of 20 is 16, because 80% is 4/5 and 20 divided by 5 is 4, multiplied by 4 is 16. Area is L x W, so 16 times 20 is 320, and don't forget unit of measurement, ft^2 for area
Answer:
The exact answer is 16.6666666667. Rounded would be about 17.

Answer:
y = 
Step-by-step explanation:
We are given the point (3, 10).
The second point is 2 on the x-axis and -7 on the y-axis. So our second point is: (3 + 2, 10 - 7) which is (5, 3).
Our formula for slope is m = 
= 
So, our equation would be 
= 
Using the standard formula of a line, y = mx + b, we can substitute for the slope, m.
y = 
+ b
Now, we can substitute a point on the line to determine the y-intercept:
Using the point (3, 10),
10 = 
+ b
b = 10 + 
b = 
So our full equation is: y =
