The slope is always m and y-int always b in a y=mx+b equation.
So: m= 3/4 and b= -2
Michael will have 4 cards left because 265/9=29.4444444... then i do 29 (from the 29.4444) times 9 which gives me 261 and i did 265-261.
Your answer is C. 3 units left and 2 units up. This is because this distance between 1 and -2 is 3 units, and the distance between 3 and 5 is 2 units. The scale factor would be 1.75, because 7 ÷ 4 = 1.75
I hope this helps
