A and F are true. because A is y=2x+7, and F is y=2x+7.
We know that the equation y=2x+7 has a point 0,7 and with the slope being 2, rise over run would make another point 1,9. And because these are linear equations if the equation y=2x+7 goes through 1,9 then it will go though -2,3 as well.
I think you are looking for a percentage but it works be about 266% or 2.66 books per month
I believe it would be 13p im not for sure though
The y intercept will be (0,-9) and the x-intercept will be (-3.5, 0)
