2. The line y = 4x - 7 crosses the y axis at: (4, 0) (0, 4) (-7, 0) (0, -7) (0,-7). if u get a graphing calculator then u would be able to solve easily. Set x=0 and solve for y to get y = 4*0 - 7 = 0 - 7 so y=7 The coordinate is (0,-7)

1. Which line is the flattest (or is less steep)? Why? y = 5x -6 y = 5x + 6 y = x - 3 y = x + 3 I think it's the last one! Parallel lines have the same slope. The first two are parallel lines with the steepest slope; the last two are parallel lines as well and would both ...

1. Which line is the flattest (or is less steep)? Why? y = 5x -6 y = 5x + 6 y = x - 3 y = x + 3 I thought it would be the last one since it has the smallest slope Well, yes...but both the third and last equations have a slope of 1, and so have the same "steepness" (...
