I said it could be c but I don't have any graph paper

campbell_st · Answer

well the distance from P to S is how far...?

rayman5766 · Answer

p is 0 and  s 14

campbell_st · Answer

so what distance is it...?

rayman5766 · Answer

oh wow I didn't put to much thought in to this now thinking about B

campbell_st · Answer

when you find it, the distance is along the y- axis... so using the scaling factor of 3 and multiply the length by 3

then that will be the new location of s on the y-axis
