Answer:
The equation of line is shown below.
Step-by-step explanation:
The equation of line is

It is the point slope form of a line, therefore the slope of the line is
and the line passing through (4,-1).
Rewrite the above equation in slope intercept form.



The point slope form of a line is

Where m is the slope and b is y-intercept.
Therefore the slope of the line is
and the y-intercept of the line is
.
Slope is defined as

Since the slope is negative, therefore the run of the line is considered on the left side. The line rise by 3 and run by 5, therefore we will add 7 in y and subtract 5 from x.
The y-intercept is
.

Therefore we have three points (4,-1), (-5,4.4) and (0,1.4). Plot the point on the coordinate plane and connect them be a straight line.
I’m pretty sure the answer is C
Well we can find the perimeter by using the formula P=2L + 2W
P=2(30) + 2(18) P=60+36 P=96
I believe we can divide the perimeter by 18 to find the total amount of lights needed.
96÷18=5.333333
So we know at least 5 lights are needed.
I'm not sure if I'm correct, but I hope this helped anyways :)
Answer:
is b
Step-by-step explanation: because x-4y
Answer:
y = -1/3x - 5
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes, so the line is:
y = -1/3x + b
Finding the value of b, using the given point (-9, -2)
-2 = -1/3*(-9) + b
-2 = 3 + b
b = -2 - 3
b = -5
The line is
y = -1/3x - 5
Hopefully, this helps!
