The graph of y=-3x + 4 is: A. a point that shows one solution to the equation.
B. a point that shows the y-intercept.
c. a line that shows only one solution to the equation.

SUBM

D

Step-by-step explanation:

An equation with both x and y in it will draw a graph, in this case a line. A line is an infinite number of points, and each point is a solution, so it is a set of all solutions.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
