Answer:

Step-by-step explanation:
The equation for slope is:

We can substitute the given coordinates into the equation:

The slope is -3
The equation for a line is:

m: slope
b: y-intercept
x, y: (x, y) coordinate pair
Now, plug in the slope and one of the (x, y) coordinate pairs to solve for the y-intercept.

Therefore the equation is:

Answer:
1000 cm²
Step-by-step explanation:
Given:
- Length = 10 cm
- Width = 12.5 cm
- Height = 8 cm
<u>Formula:</u>

Substitute the length, width, and the height of the prism to determine the volume of the prism.

Simplify the right hand side of the equation, as needed;



Therefore, the volume of the prism is 1000 cm².
The triangle is obtuse because 11 cm > 100
Basically
Other side + other side > longest side
In this case…
6 + 5 = 11 is greater than the longest side which is 10, so it would be obtuse
Hope this helps!!
