The equation y = x + a is graphed in the xy-plane, where a is a positive constant. A second equation, y = x - a, is graphed in the same xy-plane. How do the slope and y-intercept of the
graph of the first equation compare with the slope and y-intercept of the graph of the second
equation?

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

imma say 16%. sorry if its wrong. i'm doing the same stuff right now
