How do you graph Y equals 0.5x plus 1?
y = 0.5x + 1 x = -2, y = 0 x = -1, y = 0.5 x = 0, y = 1 x = 1, y = 1.5 x = 2, y = 2 Plot the points in the coordinate system, and draw the line, which is the line of the given equation.
If y is inversely proportional to the square of x fully explain what happens when x is doubled?
if INVERSELY proportional then y = 1/X^2 ( that is, 1 divided by x squared) If X doubles then X SQUARED increases as 2 x 2 = 4 times SINCE Y = 1/x^2 then Y DECREASES 4 times
An equation of a parabola that has x equals 2 as its axis of symmetry is?
How about y = (x - 2)2 = x2 - 4x + 4 ? That is the equation of a parabola whose axis of symmetry is the vertical line, x = 2. Its vertex is located at the point (2, 0).
Is point 1 4 on the line represented by the equation x plus 2y equals 5?
The equation "x plus 2y equals 5" is: x + 2y = 5 2y = 5 - x y = 5/2 - 1/2x y = -1/2x + 5/2
How do I write an equation in standard form for a line satisfying the given condition. Through -2 and 9 and -2 and 7.?
In general, if a line passes through the points (a, b) and (c, d), its equation can be written as:y - b = [(d - b)/(a - c)](x - a)In this case, however, the formula is not necessary -- and in fact, attempting to apply it in its current form would result in a division by zero error. Instead, however, we can simply note that from (-2, 9) to (-2, 7) the x-coordinate does not change. This can only be the case if the line is vertical, meaning that the x-coordinate never changes. The line can therefore be represented by the equation x = -2.
What happens when y equals x is changed to y equals x plus 2?
The whole line 'shifts up' by two units, and is parallel to the original line (same slope)
Which equation of the graph occurs when y equals x is changed to y equals x equals 2?
The diagonal line collapses into a single point on that line.
How can three pins be moved so that the 10 pins are still set up in the same conventional mannor but with the point of the triangle away from the bowler?
Imagine the set up: line 1 X line 2 X X line 3 X X X line 4 X X X X line 5 (empty) Move the pin from line 1 to the centre of line 5. line 1 (empty) line 2 X X line 3 X X X line 4 X X X X line 5 X Now move the 2 outer pins on line 4 to the outer position on line 2 line 1 (empty) line 2 X X X X line 3 X X X line 4 X X line 5 X And there you go. Except the spacings I used weren't saved. I hope you get the idea though!
What happens to mean when any score in a distribution is changed?
If there are n scores and one score is changed by x then the mean changes by x/n.
What is the correct graph for x equals 3 and x equals -2?
5
X and y intercept of x-y-2 equals 0?
x - y - 2 = 0-y = -x + 2y = x - 2The graph is a straight line. The slope of the line is [2].The line intersects the x-axis at [x=2], and the y-axis at [y=-2].
What type of line is the graph x equals -2?
A vertical line that passes through -2 on the x-axis.
What is the graph to x 2?
I understand this to mean x = 2. This is the vertical line passing through the (2, 0) or, alternatively, the vertical line passing through the point where x = 2 on the x-axis.
What is the equation of a line perpendicular to the line y equals 2x-4?
6
Why is the graph of an inverse of a function flipped over the line y x instead of another line?
Because the inverse of a function is what happens when you replace x with y and y with x.
Is there is no overlap between the graphs of y x plus 2 and y x - 2?

The equation of a line is x Minus 3y Plus 2 Equals 4. Which line is perpendicular to this line?
x-3y+2 = 4 -3y = -x+4-2 -3y = -x+2 y = 1/3x-2/3 Slope or gradient of the perpendicular line is -3 Use y-y1 = -3(x-x1) to find the perpendicular equation
