Infinitely many solutions
Step-by-step explanation:
3(x+5) = 7x + 12 - 4x + 3
3x + 15 = 7x + 12 - 4x + 3
3x + 15 = 3x + 12 + 3
3x + 15 = 3x + 15
They are the same equation, therefore there are infinitely many solutions.
Slope = 1
Step-by-step explanation:
Slope = Y2 - Y1 -6 -- 5 -6 + 5 = -1 = 1
X2 - X1 -3 --2 -3 + 2 -1
