Answer:
y=3x+1
Step-by-step explanation:
perpendicular lines=their gradient multiply to produce -1 thus:
(line 1) y= -⅓x+1. gradient is. -⅓x
(line 2) gradient = 3
y=mx+c
3=y-7
x-2
multiply both sides by x-2 to remove the denominator.
3(x-2)=y-7
3x-6=y-7
collect the like terms to remain with y in one is side
3x-6+7=y
3x+1=y
y=3x+1
