Answer:
Step-by-step explanation:
Error 1) It should be divided by 5.
x - 5 = 0
x = 5
Error 2) -3 15 0 -1 5
coefficient of x² is 0 and it is not included
<span>In 3x - y = -1
-y = -3x - 1 {subtracted 3x from both sides to get into slope-intercept form}
y = 3x + 1 {divided both sides by -1}
the slope is 3 {the number in front of the x}
The slopes are the same in both equations, therefore
the lines are parallel.</span>
Answer:
( -4 , 13 )
Step-by-step explanation:
2 ( -4 ) + ( 13 ) = 5
5 = 5
3 ( 13 ) = 15 - 6 ( -4 )
39 = 39
( -4 , 13 )
