Answer: y=9x + 26

Explanation:

Notice that for two lines to be parallel they must have the same slopes but different y intercept.

So the equation y =9x + 2 has a slope of 9 and y-intercept of 2 so using the points we can determine the y intercept of the line parallel to it to find the.

Using the slope intercept form formula which is y = mx + b we can plot in the slope and the given coordinates to solve for b.

The coordinate is (-2,8) which the y value is 8 and the x value is -2

so 8 = 9(-2) +b solve for b

8 = -18 + b

+18 +18

b = 26

The y intercept is 26 so the equation will be y=9x + 26
