Graph the equation x plus y 3?

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.


How do you Graph the line that has a slope of 5 and passes through the origin?

-- 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.


What is the importance of the y-intercept in a line?

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.


What does draw diagrams to show each functions mean?

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.


What is the slope line with equation y-5x?

If you mean: y = -5x then the slope of the line is -5 and there is no y intercept


What is the point of cotact when the line y equals 2x plus 5 over 4 meets the curve y squared equals 10xa?

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)


What is the slop of the line with equation y X?

If you mean the slope of the line with equation y = x then it is 1 and there is no y intercept


Explain why the line x4 is a vertical line?

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.


What is the slope and y-intercepect of 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.


What does the y-intercept of a line mean?

At what point the line intersects the y-intercept, in an equation y=mx+b, b is the y-intercept.


What is the slope of the line given by the equation y -3x?

If you mean: y = -3x then the slope of the line is -3


What is the slope of the line given by the equation y 2.3x?

If you mean y = 2.3x then the slope of the line is 2.3
