How do you graph #y=2x#?

Answer 1

Eva Abramson

See a solution process below:

Plot the first two points that are found by solving the equation:

First Point: For #x = 0#

#y = 2 xx 0#

#y = 0# or #(0, 0)#

Second Point: For #x = 1#

#y = 2 xx 1#

#y = 2# or #(1, 2)#

Next, we can chart the two points on the coordinate plane as follows:

graph{(x^2+y^2-0.025)=0 [-10, 10, -5, 5]}((x-1)^2+(y-2)^2-0.025)

To graph the line, we can now draw a straight line through the two points as follows:

graph{(y - 2x)(x^2+y^2-0.025)((x-1)^2+(y-2)^2-0.025)=0 [-10, 10, -5, 5]}

To graph the equation y = 2x, you can start by plotting a few points. Choose some values for x, calculate the corresponding y values using the equation, and then plot those points on a coordinate plane. For example, when x = 0, y = 2(0) = 0. So, one point on the graph is (0, 0). When x = 1, y = 2(1) = 2. So, another point is (1, 2). You can continue this process to get more points, then connect them with a straight line.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
