Answer:

y=2x+4 I HOPE THIS HELPS YA

Explanation:

m=2

To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.

Use the slope 2

and a given point (−1,2) to substitute for x1 and y1 in the point-slope form y−y1=m(x−x1), which is derived from the slope equation m=y2−y1x2−x1

.

y−(2)=2⋅(x−(−1))

Simplify the equation and keep it in point-slope form.

y−2=2⋅(x+1)

Solve for y

y=2x+4.
