Answer:
y = - 3x + 21
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 4 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes , then
y = - 3x + c ← is the partial equation
To find c substitute (7, 0 ) into the partial equation
0 = - 21 + c ⇒ c = 0 + 21 = 21
y = - 3x + 21 ← equation of parallel line

I think it 6 is the answer I don't know I'm not in middle school
Answer:

Step-by-step explanation:
If two rectangles are similar, then corresponding sides are in proportion.
Therefore we have the equation:

cross multiply

divide both sides by 54

$0.18 is the answer. How I got it was you do $4.50 over 25 ounces. Then divide the $4.50 by 25. You should get 0.18
None of these are right
y=$350 because that is her total.
m=$25 because each game cost that.
B=$200 because that's how much the console cost.
$350=$25x+$200
