Have you found the equation of the dotted and thicker line

anonymous · Answer

i havent ... and I'm not sure how /: @dan815

dan815 · Answer

Have you see this equation before
y=mx+b 
or
(y-y1)=m(x-x1)

anonymous · Answer

yes

dan815 · Answer

Which one do you know how to use?

anonymous · Answer

umm y = mx + b

dan815 · Answer

Okay so pick any 2 convenient points on the line. And find the slope for those 2 points and what the y-intercept must be(The y-intercepts are already given in fact).

dan815 · Answer

The bottom line will be an less than or equal sigh, as its not dotted
The above line, will be a greater only sign, since it is dotted and all the data is above the line.

dan815 · Answer

y=mx+b,(m= solve, b= y-intercept)

Need any more clarification on how to find the slope of the line?
