Answer:
no solution
Step-by-step explanation:
x+3y =9
Solve for y
Subtract x from each side
3y = -x +9
Divide by 3
3y/3 = - 1/3x +9/3
y = -1/3x +3
The y intercept is 3 and the slope is -1/3
3x+9y = 45
Subtract 3x from each side
9y = -3x +45
Divide each side by 9
y = -3/9 x +45/9
y = -1/3x +5
The y intercept is 5 and the slope is -1/3
There is no solution
The lines are parallel (same slope) but the y intercepts are different
