Answer: y=(-1/2)x-6.5
Explanation:
y=2x-6
the perpendicular to this will have the opposite reciprocal slope.
The new equation will be
y=(-1/2)x-b
--------------------------
To find the y-intercept of the equation, we should substitute the point into the equation (5,4)
y=(-1/2)x-b
4=(-1/2)×5-b
4=-2.5-b
b=-6.5
------------------------------
so the equation will be y=(-1/2)x-6.5
