The slope is -1/2. I know this because slope intercept of a line is y = mx + b. In the equation, y = -1/2 + 1/4, the slope is -1/2 and the y intercept is 1/4.
m stands for slope
b stands for y intercept
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
