Question

Find the equation of the line that is parallel to the glven line and passes through the given point.

y = -x +4; (2,5)

Answer 1

y = -x + 7

Explanation:

Slope is the same for every parallel equation,

so just do y = -x + n

n means a number, since we don't know the y intercept of the parallel line yet.

Now we plug in a point, (2,5), 2 for the x and 5 for the y.

So 5 = -2 + n

solve for n

n = 7

Now we have our equation. y = -x + 7
