A line passes through the point (0, 0) and has a rise over run ratio of 4/3. Give two other points that the line passes through​
Sergio [31]

Answer:

(3,4) and (6,8).

Step-by-step explanation:

Rise is equal to y and run is equal to x. If the fraction is 4/3, y is equal to 4 and 3 is equal to x. 3 across is 3 and 4 upwards is 4. Just keep adding 3,4 to get the following points the line passes through. Since we need two points, 3,4 and 6,8 would be the appropriate answers.
