The equation of the line in function notation is y.=-2x + 5
Equation of aline
The standard equation of a line is expressed as y = mx + b
where
m is the slope
b is the y-intercept
Given the equation
2y=x-4
y = 1/2x - 2
The slope perpendicular will be -2
Substitute into y-y₁ = m(x-x₁)
y-(-7) = -2(x-6)
y+7 = -2x +12
y = -2x + 5
Hence the equation of the line in function notation is y.=-2x + 5
