On a coordinate grid, both point (1, 2) and point (−3, −3) are reflected across the y-axis. what are the coordinates of the reflected points? (−1, 2) and (3, −3) (−1, −2) and (3, 3) (1, −2) and (−3, 3) (1, 2) and (3, 3)

The coordinates of the reflected points are:

          (-1,2) and (3,-3)

When we reflect the figure across the y-axis then the rule of the transformation is given by:

                 (x,y) → (-x,y)

i.e. each point on the figure is transformed as the x-coordinate of the point takes the opposite sign and the y-coordinate remains the same.

Hence,

(1,2) → (-1,2)

and (-3,-3) → (-(-3),-3)

i.e.

(-3,-3) → (3,-3)

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
