write an equation of the line that passes through the given point and is parallel to the given line and perpendicular to the given line.
(-1.4) y=-x-4
(-1.4) y=-x-4
-
The line is in y = mx + b form.
So the slope is m = -1
You need to be parallel so the the slope is m = -1
Now use the equation y = -x + b. Substitute in x and y to find b. ==>
4 = -(-1) +b ==> b = 3 ==>
y = -x + 3
