Write an equation that is parallel to y=-4x+5 and passes through the point (-2,-1)
1 answer:
The equation of line parallel to y=-4x+5 is y = -4x-9
Further explanation:
Given equation of line is:
y = -4x+5
Comparing it with the standard form of equation
As the slopes of parallel lines is equal, the slope of the line parallel to given line will be same. Putting the value of slope in standard equation.
To find the value of b, the given point will be put in the equation
Putting the values of b and m in standard form
So, the equation of line parallel to y=-4x+5 is y = -4x-9

Answer:
Grant will make $60 from selling 12 magazines.
Step-by-step explanation:
Let m represent number of magazine sold and A represent amount of money earned.
We have been given that Grant earns $5 for each magazine he sells. So amount earned from m magazines would be 5 times m that is dollars.
Now, we will equate total amount earned by Grant with A as:
Therefore, our required equation would be .
To find the amount earned by Grant by selling 12 magazines, we will substitute in our equation as:
Therefore, Grant will make $60 from selling 12 magazines.
