Answer:
(−3)(7+1)
Step-by-step explanation:
Set up the porportion: x/120= 40/100
Cross multiply: 100x=120 times 40
Answer:
y = -3x + 4
Step-by-step explanation:
y = -3x - 1
a parallel line is going to look identical to the previous equation except for the last number.
for example,
y = -3x + 10
and
y = -3x - 2
are both parallel lines
now, substitute y and x for the points of the coordinate given.
y = -3x - 1
-8 = -3*4 - 1
-8 = -12 - 1
this equation isn't true.
so change the last number to make it true
-8 = -12 + 4
-8 = -8
so, your new equation is
y = -3x + 4
