What type of lines are these y equals 2x plus 4 and 12 equals 2y plus x?
If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines
What is the answer to - 2x - y - 3?
-1
What type of lines are these x plus 2y equals 7 and 2x - y equals 7?
x + 2y = 7 2y = -x + 7 y = -(x-7)/2 => -x/2 + 7/2 2x - y = 7 -y = -2x + 7 y = 2x + 7 Since -1/2 is the negative reciporical of 2, the slopes of these equations are perpendicular. Therefore, these two lines are perpendicular.
What does shading on a graph signify?
If this is related to coordinate geometry then the shading refers to the areas on the graph that satisfy the given inequations i.e if y>=2x+3 and y>= -2x+3 then the areas above both lines would be shaded.
How do you factor 4x2 -y2-6y-9?
It is (2x +y + 3)*(2x - y - 3).
What type of lines are these y equals 2x and y-2x equals 3?
parallel
What type of lines are these y equals 2x and y equals 2x-1?
They are parallel lines
What type of lines are y 2x and y 4x 2?
Straight lines.
Are lines y equals 2x and y - 2x equals 3 perpendicular or parallel?
y-2x=3 -y -y -2x=3-y -3 -3 -2x-3=-y /-1 /-1 2x+3=y y=2x and y=2x+3 have the same slope of 2, so they are parallel. Hope this helps! ;D
Which type of lines are these y equals 2x and y equals 2x-1?
They are parallel lines with a vertical separation of 1.
What type of lines are these y 2x and y 2x -1?
As stated these are not lines, but just a collection of algebraic terms. If we change them to y=2x and y=2x-1, then on a graph of y versus x, these are parallel lines separated by vertical distance of 1.
Are lines y equals 2x and y 2x equals 3 perpendicular or parallel?
If the second equation is: y minus 2x equals 3, then:y - 2x = 3 ⇒ y = 2x + 3 and it is parallel to y = 2x.Otherwise (with with missing operator as "plus", "multiply" or "divide"), the lines are neither parallel nor perpendicular.
What type of lines are these y2xand y2x-1?
If you mean y = 2x and y = 2x-1 then they are parallel lines because they have the same slope.
What lines are parallel y equals 2x plus 3?
If two lines have the same slope (ie. they rise or fall at the same angle) they are parallel.With lines, the number before the x determines the slope. So as long as your line has a 2x term, and is written in the same form as y = 2x + 3, it will be parallel.Therefore,y = 2x + 7y = 2x +5556y = 2x - 3y = 2x - 0.7561... are all parallel lines to y = 2x + 3
What type of lines are these y equals 2x plus 4 and 12 equals 2y plus x?
If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines
4x-3y equals -1 y-2x equals -3?
Assuming you want to find the point at which those two lines intercept: We are told: y - 2x = -3 ∴ y = 2x - 3 We are also told: 4x - y = -1 ∴ 4x - (2x - 3) = -1 ∴ 2x - 3 = -1 ∴ 2x = 2 ∴ x = 1 Now we know the value of x, and can plug it back into either of the original equations to find y: y = 2x - 3 ∴ y = 2 - 3 ∴ y = -1 So the lines defined by these equations intercept at the point (1, -1).
