Answer:
yea what do you need help with?
Step-by-step explanation:
See the blue dot in the attached image.
First, find the x value on the coordinate plane. The x value is the first number in the point coordinates, so in this case, it is 4. Move to the right 4. (If it was negative, you would move to the left.)
Then, find the y value, which is the second number of the coordinates. In this case, it is -1, so move down 1. (If it was positive, you’d move up.)
Now, mark this point. This is (4, -1).
Answer:
Step-by-step explanation:
The equation for this is 3x + 5x + 4x = 600 where x is the same amount of money multiplied by the scalar value to ensure the money is divided in that ratio exactly. That gives us 12x = 600.
x = 50.
The largest value is 5(50) = 250 and
the smallest value is 3(50) = 150.
The difference between these is $100.

Step-by-step explanation:
(3)
Parallel lines have equal slopes
the equation of a line in sloipe- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x + 5 ⇒ m = 
y = 4x + 5 ⇒ m = 4
y = - 4x + 5 ⇒ m = - 4
y = - 4x - 9 ⇒ m = - 4
the 3rd and 4th options have equal slopes and are parallel
(4)
given a line with slope m then the slope of a line perpendicular to it is
= - 
y =
x + 4 ⇒ m = 
y = -
x + 5 ⇒ m = - 
y =
x + 3 ⇒ m = 
y = 6x + 3 ⇒ m = 6
note that a slope of m = 6 , has a perpendicular slope of
= - 
the 2nd and 4th lines are perpendicular
