All you do is turn 4.12 into a whole, make it over 100 and simplify.
So, 4.12
= 412/100
Which simplifies to 103/25.
Answer: The constant of proportionality is 3.5, so your answer would be B.
First, distribute -2 into the parentheses which gives you y+4=-2x+2. Subtract 4 to both sides and you get y=-2x-2. This would be the slope-intercept form of the original equation.
