# What is the equation of a line passing through (2, -1) and parallel to the line represented by the equation y = 2x + 1

Answer from: EbonyMontricee

Step-by-step explanation:

Two parallel lines do not cross and therefore have the same slope. For the line y=2x+1, the slope is 2. Substitute 2 and the point (2,-1) into the formula

y = 2x - 5

Step-by-step explanation:

The equation has to have the same slope -- in this case, it is 2 -- to be parallel to 2x - y = 4.

Now we have y = 2x - k.

Then, we plug in the coordinates to our new equation to solve for k.

-1 = 2(2)-k

-1 = 4-k

k = 5

So the final equation would be y = 2x - 5

Sherina wrote and solved the equation. x-56=230 x-56-56=230-56 x=174 what was sherina’s error? sherina’s work is correct. sherina only needed to subtract 56 from 230. sherina made a subtraction error when subtracting 56 from 230. sherina should have added 56 to both sides of the equation.
