3x - 2y = 11


Here we will show you how to calculate and provide solutions to math problems related to 3x - 2y = 11.

We will start by calculating and showing you the solution for the x-intercept and y-intercept of 3x - 2y = 11.

Then, we will show you how to get the graph plot coordinates for 3x - 2y = 11 so we can illustrate it on a graph.

Finally, we will solve 3x - 2y = 11 for x and also for y, then calculate and show you the solution for the slope of 3x - 2y = 11.




Find x-intercept
The x-intercept is where the graph crosses the x-axis. To find the x-intercept, we set y1=0 and then solve for x.

3x - 2y = 11
3x - 2(0) = 11
x1 = 3.667    y1 = 0

Find y-intercept
The y-intercept is where the graph crosses the y-axis. To find the y-intercept, we set x2=0 and then solve for y.

3x - 2y = 11
3(0) - 2y = 11
y2 = -5.5    x2 = 0




Get Graph Plot Coordinates
Getting two graph points will allow you to make a straight line on a graph. The plot coordinate format is (x1,y1) and (x2,y2).

Thus, we use the x-intercept and y-intercept results above to get the graph plots for 3x - 2y = 11 as follows:

(x1,y1) and (x2,y2)
(3.667,0) and (0,-5.5)




Solve for x
To solve for x, we solve the equation so the variable x is by itself on the left side:

3x - 2y = 11
x = 0.667y + 3.667

Solve for y
To solve for y, we solve the equation so the variable y is by itself on the left side:

3x - 2y = 11
y = 1.5x - 5.5



Find slope
The slope of the line (m) is the steepness of the line. It is the change in the y coordinate divided by the corresponding change in the x coordinate. Simply plug in the coordinates from above and solve for m to get the slope for 3x - 2y = 11

m = (y2 - y1)/(x2 - x1)
m = (-5.5 - 0)/(0 - 3.667)
m = 1.5
