Find the equation of a line which cuts the x-axis at a distance of 3 units to the left of the origin andhas a slope equal to -2?
y = mx + b
m = slope
y = -2x+b
when y = 0, x = -3
0 = -2(-3)+b
b = 6
y = -2x +6

An equation is equal if you have a math problem on each side of an equal sign.
How do you find the equation of a circle?
A circle is the locus of all points equidistant from a fixed point on the plane. The fixed point is called the centre of the circle and the equal distance is called the radius of the circle. We can derive the equation of the circle from the distance formula. Let O be the centre of the circle and r be the radius of the circle. Here the centre = Origin = (0, 0) and the radius = r units. The distance r = sqrt ((x-0)2 + (y-0)2) r = sqrt (x2 + y2) Squaring both the sides, we get x2 + y2 = r2 This is the equation of the circle with centre as Origin. If the centre point is some (h, k), then use the distance formula to find the radius r. The distance r = sqrt ((x-h)2 + (y-k)2) Squaring both sides, we get (x-h)2 + (y-k)2 = r2. This is the equation of the circle with centre as the point (h, k).
What is the distance when time is equal to 15?
To determine the distance when time is equal to 15, we need a specific equation or context, such as speed or rate of travel. For example, if the speed is constant at 5 units per time unit, the distance would be calculated as distance = speed × time, resulting in a distance of 75 units. Without additional information, the distance cannot be accurately determined.

What does work divided by force equal?
Work divided by force equals distance. This equation is based on the formula for work, which is work = force x distance. By rearranging the formula, you get distance = work/force.
How does one find out if an equation's graph goes through the origin?
-- Take the equation -- Set either 'x' or 'y' equal to zero -- Solve the resulting equation for the remaining variable -- If the remaining variable is then also zero, then the origin is on the graph of the function If the graph is a straight line ('x' and 'y' appear in the equation only to the 1st power), then the equation has to be in the form of a simple ratio ... like (y = Kx) or (x = Ky) or (xy = K) or (x/y = K) ... in order to go through the origin.
How is an equation equal?
An equation is equal if you have a math problem on each side of an equal sign.
What would the graph for the equation y2x look like?
If y is equal to 2x, the graph would be a straight line going through the origin. The line would go up and to the right, and the angle at the origin has a tangent equal to 2. This angle is between 63 and 64 degrees.

What is the energy force equation that describes the relationship between energy and force?
The energy force equation that describes the relationship between energy and force is: Work (energy) Force x Distance. This equation shows that the amount of work done (energy) is equal to the force applied multiplied by the distance over which the force is applied.
What is an equation called that doesn't have an equal sign?
If it doesn't have an equal sign, then it's not an equation.
When does an equation not equal to each other?
