If I were to graph this equation
y= 2x + 0.5 would I graph x as 2 and y as .5?
to get y values you have to put the x values into the y equation. Y is a function of x.
So for
x=1,y=2.05.
x=2, y=4.05.
x=3, y=6.05.
x=4,y=8.05.
x=5,y=10.05.
x=6,y=12.05.
Does that clear things up?
thank you so much pete
you're welcome!!
the value of x is 1, 2, 3, 4, 5, 6 etc. on the graph. it is the same for y
To graph the equation y = 2x + 0.5, you need to understand the relationship between x and y and plot several points on the coordinate plane.
To find the values for x and y, you can choose different values for x and substitute them into the equation to solve for the corresponding y-values.
Let's choose a few arbitrary values for x to get started:
1. When x = 0:
Substitute x = 0 into the equation: y = 2(0) + 0.5 = 0.5
So, we have the point (0, 0.5).
2. When x = 1:
Substitute x = 1 into the equation: y = 2(1) + 0.5 = 2.5
So, we have the point (1, 2.5).
3. When x = -1:
Substitute x = -1 into the equation: y = 2(-1) + 0.5 = -1 + 0.5 = -0.5
So, we have the point (-1, -0.5).
Now, plot these points (0, 0.5), (1, 2.5), and (-1, -0.5) on the coordinate plane.
The x-axis represents the horizontal values, and the y-axis represents the vertical values. Then, connect these points with a straight line to create the graph of the equation y = 2x + 0.5.
Note: Graphing more points can give you a better understanding of the shape and direction of the graph.
no, you have to plug in the values for x to get values for y. For instance, if you want x is 2, then y would have to be y=2(2)+.05 which is 4.05. If you want x as 1, y=2.05.
Does that make sense Island G?
