Answer: y = -2x - 7
Step-by-step explanation:
The equation for a perpenducular line has a slope that is the negative inverse of the reference line, in this case x - 2y = 6.
Let's put this equation into standard slope-intercept form, y = mx+b, where m is the slope and b the y-intercept (the value of y when x is 0).
x - 2y = 6
- 2y = 6 - x
y = (1/2) x -3
The slope is (1/2), so a perpendicular line will have a slope of -2.
y = -2x + b
We can find b by using the given point ((-3,-1), a known solution):
-1 = -2*(-3) + b
-1 = 6 + b
b = -7
The perpendicular equation is y = -2x - 7
y = -2x
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.Jan 8, 2019

Answer:
£7,878
Step-by-step explanation:
she gets:
40p× 260 miles = 10,400p
she pays:
52 : 5.36= £9.70 per mile
260 x 9.70 = £2,522
to find out what she claimes more than she pays: 10,400 - 2,522 = 7,878
The answer is D. because first you got solve the problem.
y=2.5x
(turn y to 0)
0= 2.5x
÷2.5 ÷2.5
_________
0=x
So we got one answer (0,0)
y=2.5x
(turn x to 0)
y= 2.5(0)
y=2.5
(2.5, 0)
When you do (0,0) (2.5,0) on the graph it will look like D.)
the answer to the question is F= -5.37
