Please include a chart similar to the image below. Question is in the image below
yawa3891 [41]

Step-by-step explanation:

<u>Given:</u>

  • Total distance is 500 km
  • Total time is 5 1/2 h
  • The distance travelled at 100 km/h is x
  • The distance travelled at 80 km/h is y

<u>We know that:</u>

  • Time = distance / speed

<u>Considering all the info we can make below chart:</u>

Nikolas' car trip                                                                    

<u>                         |    at 100 km/h  | at 80 km/h |  Total       |</u>

<u>Distance            |         x              |      y            |   500 km  |</u>

<u>Time                   |      x/100         |     y/80       |     5 1/2 h   |</u>

Is it parallel or is it perpendicular?
zavuch27 [327]
It is parallel, which means that the new line should have the same slope of the given line y=-5/4  x+7
and the slope is the coefficient of x 
so the slope = -5/4
in order to solve this problem we have to know the equation of the slop
slope=  \frac{y-y1}{x-x1}
where (x1,y1) is the point by which the new line passes through 

\frac{-5}{4}=\frac{y-(-4)}{x-1}
\frac{-5}{4}= \frac{y+4}{x-1}
-5(x-1)=4(y+4)
-5x +5=4y+16 (by subtracting 16 from both sides)
-5x -11= 4y (divide both sides by 4)
y= \frac{-5}{4}x - \frac{11}{4}
