Question 94429
Graph y = 2x-3 on a coordinate plane.
This is quite easy to do on your own coordinate graph paper. This is a linear equation (you can tell this because the highest power of the independent variable, x, is 1) and since you need only two points to define a straight line, you would just assign a value to x and solve for the corresponding value of y to give you one point (x, y) then do this again with a different value of x to get the second point.
Plot these two points on your graph paper and draw the straight through them.
Let's pick x = 0 for the first point. Plugging this into your equation, we can solve for the corresponding value of y, the dependent variable.
For x = 0
y = 2(0)-3
y = -3
The coordinates of the first point are (0, -3) and...
For x = 3
y = 2(3)-3
y = 6-3
y = 3
The coordinates of the second point are (3, 3)
The graph appears below:
