Answer:
A y = -x+2
Explanation:
To find the slope of the line m we use the formula
slope = (y2-y1)/(x2-x1)
= (-9--7)/(4-2)
= (-9+7)/(4-2)
= -2/2
= -1
When lines are parallel, the slopes are the same. We need to find a line with slope of -1
y = -1x+2 is written in the form y =mx+b where m is the slope
m=-1 so the slope is -1
This line has the same slope so it is parallel to the line above.
