Answer:
solution is (10/3 , -7/3) for y = (1/2)x - 4 and y = 2x - 9
Explanation:
y = (1/2)x - 4
y = 2x - 9
2x - 9 = (1/2)x - 4
(3/2)x = 9 - 4
(3/2)x = 5
x = 10/3
y = 2*(10/3) - 9 = 20/3 - 9 = 20/3 - 27/3 = -7/3
solution is (10/3 , -7/3) unless you meant to write y = x - 4 and y = 2x - 9
if so then x - 4 = 2x - 9 x = 5... but this is not in your solution set.
