y = - 4x - 2
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - 4x - 5 is in this form
with slope m = - 4
• Parallel lines have equal slopes
y = - 4x + c ← is the partial equation
To find c substitute (- 2, 6 ) into the partial equation
6 = 8 + c ⇒ c = 6 - 8 = - 2
y = - 4x - 2 ← equation of parallel line
Answer:
Step-by-step explanation:
(a^2 - 5ab) - (7 - 3ab) + (2ab - a^2) = -7
a^2 - 5ab -7 +3ab + 2ab -a^2 = -7 [combine like terms]
a^2 - a^2 = 0
-5ab + 3ab + 2ab = 0
-7 = -7
Answer:
y = 14
Step-by-step explanation:
move 5y over to the left and you should get -2y +6=-18. subtract 6from both sides and you will now have -2y=-24. divide bothe sides from -2 and you will get y=14
