We must remember that 50 x 2 = 100. Multiplying numbers by 100 would be easier since all we have to do is add two zeros after. For example, 62 x100 = 6200.
Since we multiplied a number by 2, we must divide it by 2 after getting the product. To make this more clearer, for 12 x 50, for example, we have
12 x 50 = (12 x 100)/2 = 1200/2 = 600

Answer: y = 4x + 5
Step-by-step explanation:
Rearranging 4x-y = 1 we get y = 4x-1 as the equation of the line.
Since the new line is parallel to y=4x-1, that means the slopes are equal. Therefore, the slope of the line is 4.
So, the equation of the line is y = 4x+b
To figure out b, we can plug in the point (-2,-3) into the equation.
So -3 = -2*4 + b
-3 = -8 + b
And we get b = 5.
Therefore, the equation of the line is y = 4x + 5
