If Michael can travel 18 blocks on her skateboard in 6 minutes, how far can he go in 9 minutes?

First, find the unit rate (how many blocks Michael can travel in 1 minute)

that can be found using the equation 18/6 = 3. Michael can travel 3 blocks/minute

then, multiply the blocks he can travel in 1 minute by 9 to get the number of blocks he can travel in 9 minutes

3 x 9 = 27

Michael can travel 27 blocks in 9 minutes.

Y= -2x-1 the negative in front of the 2 is because the slope is negative and the -1 is because it’s down 1 on the y axis.
