y=10x+175, After 50 minutes 675 puzzles would be placed.
Work Step by Step
M=10 B=175 A)175 puzzle pieces are already placed so 175 is the y-intercept. 10 puzzle pieces are placed per minute so 10 is the slope. Make the equation using M and B: y=10x+175 B)Plug in x=50 to find out how many pieces are done after 50 minutes: y=10x+175 y=10(50)+175 y=500+175 y=675 Y=10x+175
