Graph the linear equation: - x + 3y = 5
yKpoI14uk [10]
 its easiest if you put it in y = mx + b form, where b is the number you plot on the y axis and m is your slope. 
rearranging... 
x + 3y = -5 3y = -x - 5 y = -1/3 x - 5/3 
so your b value is -5/3, which is where you'll plot a point on the y axis. the slope is -1/3 
since slope is rise over run, [and this case its negative] you'll go down 1 and to the right three. 
edit: then draw a point there, connect the points, and you'll have a line =]

Marking Brainliest!<br><br>How do I calculate area on uneven shapes?
STatiana [176]

Answer: 325mm

Step-by-step explanation:

To calculate shapes like this, you need to find the area of each of the shapes and add them.

The bigger square is 15 * 15 = 225

The smaller square is 10 * 10 = 100

Then add them: 225 + 100 = 325
