Answer:
Below.
Step-by-step explanation:
The slope is given by the coefficient of x (= 3/4) .
If the slope changes to -3/4 the line will slope in the opposite direction.
If the slope is 3/4(positive) it rises to the right and if it is -3/4 it will rise to the left, but will rise at the same rate.
The 2 lines will cross each other when 3/4x - 7 = -3/4x - 7:
3/4x - 7 = -3/4x - 7
6/4 x = 0
x = 0
So they will cross at the point (0, -7).
