Question 777377: Line a is given by equation y=3x-7 and line b contains the points (0,5) and
(2,9) Which of the two has a greater slope?

You can put this solution on YOUR website!
Slope of y = 3x - 7 = 3
Using slope equation:
y2 - y1/x2 - x1
9 - 5/2 - 0
4/2 = 2
tan^-1x = 3
x = 71.6 degrees.
tan^-1x = 2
x = 63.4 degrees
y = 3x - 7 has the greater slope
Hope this helps.
