Answer:
Equation: y = x + 4.
Step-by-step explanation:
Let the equation will be y = mx + c, where m is the slope of the equation and c is the constant.
The perpendicular equations' slope's multiplication is -1.
Since the above equation needs to be perpendicular to the given equation, the slope of the equation, that is m = -1(As the slope of the given equation is 1).
It is given that, the equation passes through (4, 8).
[tex]8 = 4\times1 + c\\c = 4[/tex].
Hence, the equation is y = x + 4.
It is slope intercept form.
