Answer:

y = 2x +12

Explanation:

You want the line through point (-3, 6) that is parallel to y = 2x -7.

Parallel line

The given line equation is in slope-intercept form ...

y = mx + b . . . . . line with slope m and y-intercept b

This allows us to see that its slope is 2.

The parallel line will have the same slope. All we need to do is find its y-intercept.

Intercept

Solving the above equation for 'b', we get ...

b = y - mx

Using (x, y) = (-3, 6) and m = 2, we find 'b' to be ...

b = 6 -(2)(-3) = 12

Equation

Using the values for m and b that we now know, the desired equation is ...

y = 2x +12
