-- Put a dot at the point where (x=1, y=5). -- Move your ruler so that the dot and the origin are both on the edge of the ruler. -- Draw a line along as much of the ruler as you want to. That line is the graph of y = 5x, which is the equation of the line you're describing.
If you mean: y = -5x then the slope of the line is -5 and there is no y intercept
If you mean a line of y = 2x+5/4 and a curve of y^2 = 10x Then it works out that the line touches the curve at: (5/8, 5/2)
The slope of a line is its "rise over run", or the ratio of its change in y to its change in x. The y intercept is a point where a line intersects the y axis.
At what point the line intersects the y-intercept, in an equation y=mx+b, b is the y-intercept.
Put a dot on the x axis at x=3 and a dot on the y axis at y=3 and draw a straight line between them.
-- Put a dot at the point where (x=1, y=5). -- Move your ruler so that the dot and the origin are both on the edge of the ruler. -- Draw a line along as much of the ruler as you want to. That line is the graph of y = 5x, which is the equation of the line you're describing.
It tells where on the y-axis the point goes. In Y = -2x + 3, the y-intercept is 3, which tells you to put the dot on the point 0,3.
Here are some simple functions. 1. x=5 2. y=-3 3. z=x+iy for x=3 and y=8 Here are the diagrams: 1. A dot at x=5 on the real number line 2. A dot at y=-3 on the vertical number line. 3. Move 3 units on the x-axis and up 8 units to y=8 and put a dot. A more complex diagram would be drawn for a function like y=sin x and would be a "sin" wave.
If you mean: y = -5x then the slope of the line is -5 and there is no y intercept
If you mean a line of y = 2x+5/4 and a curve of y^2 = 10x Then it works out that the line touches the curve at: (5/8, 5/2)
If you mean the slope of the line with equation y = x then it is 1 and there is no y intercept
x = 4 is the set of all points where the x coordinate = 4 On a number line, it's easy to graph. You simply place a dot on the number 4. When you extend that number line along the y axis, the dot extends, as well, into a line.
The slope of a line is its "rise over run", or the ratio of its change in y to its change in x. The y intercept is a point where a line intersects the y axis.
At what point the line intersects the y-intercept, in an equation y=mx+b, b is the y-intercept.
If you mean: y = -3x then the slope of the line is -3
If you mean y = 2.3x then the slope of the line is 2.3
