Respuesta :
y = (1/2)x + b
9 = (1/2)(-3) + b
9 = (-3/2) + b
10 1/2 = b
y = (1/2)x + 10 1/2
9 = (1/2)(-3) + b
9 = (-3/2) + b
10 1/2 = b
y = (1/2)x + 10 1/2
Answer:
Step-by-step explanation:
Given line is y =-2x+8
By comparing the given line with the slope intercept equation y=mx+b we get that the slope of the given line is m = -2
The concept is slope of a perpendicular line is -1/m
so slope of line perpendicular to the given line must be =-1/-2 = 1/2
so now we need a line with slope 1/2 and that passes throuh (-3,9)
Point slope equation is
y-9 =1/2(x-(-3))
[tex]y-9 = \frac{1}{2} (x+3)[/tex]
