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:
The exchange rate for Dollars to Euros is of 1.33.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
Exchange rate for Dollars to Euros.
We want to find the number of dollars in a euro.
In 375 euros, there are 500 dollars, so how many dollars in 1 euro?
375 euros - 500 dollars
1 euro - x dollars
Applying cross multiplication:



The exchange rate for Dollars to Euros is of 1.33.
The disciminant is x=-8/5
