Use intercepts to graph the line described by the equations-2x-4y=8

tekilochka [14]

-- The x-intercept is the point where the line crosses the x-axis.
So y=0 there.

 -2x - 4y = 8
 -2x - 4(0) = 8
 -2x = 8

Divide each side by -2 : x = -4 => the x-intercept is (-4, 0)

-- The y-intercept is the point where the line crosses the y-axis.
So x=0 there.

 -2x - 4y = 8
 -2(0) - 4y = 8
 -4y = 8

Divide each side by -4 : y = -2 => the y-intercept is (0, -2)

Now you have two points on the graph ... the points where the line crosses each axis.

Mark little dots at both points, then lay your ruler across both dots, and draw
the line along the edge of the ruler, as far as you want to in both directions.

Identify the slope and y-intercept of the line whose equation is given. write the y-intercept as an ordered pair. y = negative 2

PSYCHO15rus [73]

The line having the equation, y = -2x + 5, has a slope = -2, and y-intercept = (0, 5). Thus, option A is the best choice.

The slope of a line is the tangent of the angle that the line makes with the positive side of the x-axis.

The y-intercept of a line is the point at which the line intersects the y-axis.

The standard form of a line is y = mx + b, where m represents the slope of the line, and b represents its y-intercept.

In the question, we are asked to identify the slope and the y-intercept of the line whose equation is y = -2x + 5.

Comparing the given equation of the line, y = -2x + 5, with the standard equation of a line, y = mx + b, we can say that,

m = -2, and b = 5.

Representing b as an ordered pair, we get (0, 5), as b represents the y-intercept which is a point on the y-axis, where the x-coordinate is always equal to zero.

Thus, we get the slope = -2, and the y-intercept = (0, 5).

The option representing the answer is option A.

1x1 is 1. 1x2 is 2. Why is this? Use 2 sentences and briefly explain.

lianna [129]

"1 x 1" means whatever you want it to mean. There is nothing that says the operation "x" should be multiplication. There is nothing that says that "1" should even be a number. I could, just to be a regular A-hole, say that "1" is shorthand for a set of elements, and "x" is just a nice way of pairing "1" with itself, and I can call this a domain for a function I am about to define.

However, if we are being totally serious here, "x" means the operation of multiplication and "1" is a commonly understood concept referring to the idea of a single thing by itself. Multiplication is a short-cut for lengthy addition problems.

So 3x4 is a short cut for 3 + 3 + 3 + 3, or equivalently, 4 + 4 + 4. That's pretty much it. How many times do I add up 3? How many times to I add up 4?

So when you ask what is "1 x 1", you are really asking How many times do I add up 1? Well, you add up 1 just 1 time. That gives you 1.
