Step-by-step explanation: Assuming that the bus continues at a steady rate, the bus travels 126 miles in 7 hours. One way to find this is to divide 36 by 2 to find how many miles the bus travels in 1 hour. The answer to this is 18. If you then multiply 18 by 7, you get 126. The other way to find this answer is to divide 7 hours by 2, which is 3.5; this means that the bus is traveling for 3.5 trips of 2 hours or 7 hours in total. Multiply 36 by 3.5 and you will also receive 126. Hope this helps!
The equation for a line in slope-intercept form is , where is the slope and is the y-intercept. This means that the slope of is 4/3.
We would like to find a line parallel to which passes through the point (12, 3). Any parallel line must have the same slope, so the equation for the new line will be for some number . We know that must be equal to 3 when is equal to 12, so 3 = (4/3)(12) + b. This means that 3 = 16 + b, so b = -13.
Therefore, the equation for the parallel line is .
