Choose the equation that represents the line that passes through the point (6,-3) and has a slope of 1/2
a y=1/2x+6
b y= 1/2x-6
c y=1/2x-3
d y=1/2x+3

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
