Answer:
-2/5
Step-by-step explanation:
The slope calculator helps find the slope of any line through two given points. ... two points that this line passes through, use our slope intercept form calculator. ... Simplify the fraction to get the slope of -2/5 . ... The calculations in finding the slope are simple and involves nothing more than basic subtraction and division.
Answer:
it depends
Step-by-step explanation:
The required tools are a compass and straightedge. A pencil or other drawing tool will also be useful (or you can use the marker in the compass).

Generally, follow the applicable directions. The specific directions vary, depending on the construction you want to do. Numerous web sites and videos can show you step-by-step. (Search for "construction of ...") for whatever you're trying to construct.

To construct a circle (or part of a circle), set the compass to the appropriate width, place the pointed end on the center of the circle, and rotate the marker in a circle around that point, taking care to ...
- keep the pointed end in the same spot,
- keep the width of the compass the same until your circle is complete.
To construct a line through two points, align the edge of the straightedge with the two points, and make a mark along that edge using your marking tool. (You may find that you need to make a slight adjustment in your alignment to account for the width of the marker).
All other constructions use combinations of these skills.
425 cm. The ratio is 17 : x is equal to 2cm : 50cm. You use cross multiplication to solve. 17 times 50 = 2 times x.
850 = 2x
425 = x
Solution: We are given that:
5 people can paint 7 walls in 21 minutes
Therefore, 1 person can paint 7 walls in
minutes
Which means 1 person can paint 1 wall in
minutes
Now, 3 people can paint 1 wall in
minutes
Therefore, 3 people can paint 5 walls in
minutes
